Haha, try ride NS2R :-D they are much worse than AR1 :-D

Some people see a half empty glass.. I like to see a half full glass

Natural way for every bimmer owners wanting to upgrade

Alright, time to gve a little extra verdict on the CR-S. A few days ago, we had low temperatures, but full sun and dry road surfaces. Temps where +4 degrees. I did a short drive, 20-30kms, going to fuel the car, and then drove some back roads, with more bumps and twisty roads. Alright, as soon the tires got to just about palm heat ca 30degrees or so, the rubber goes from very hard, to a delicate soft touch. Think of ar1 soft when ar1 is stored cool. With the temps around palm warm, the grip was coming in nicely, tire seems to be more predictable. I didn't push on at all, i just tried to feel the dynamics.. The sidewalls are pretty stiff, but so far, i don't feel the tire rides as hard as the ar1. My friend Henning, used sometime ago a phrase, that the AR1 feels like riding on concrete tires. The CR-S doesnt have this feelign when they gets a little heat. They do have that feeling when they are very cold and the surface are damp, but that is not a surprise, when you feel the rubber is very hard from the manufaturing process but also stored cold. Ive parked the car up again for several weeks, snow just landed here 2 days ago, again, so testing is set on pause so far. I still feel the tires remind me of cup2, but with more feedback, and less mushy feel. I have to say, cup2 is not a tire i would like to drive, so with the CR-S distincing further away from them, is imo a very good sign. Noise level are still very low, i do prefer a tire that is loud, because my diff screams so much, that its hard to hear the tires squeeling in the corners. So for me its a new learning curve. But i am going to address the noise of the diff, to lower it a bit. Involving a plate over the axle containng some sound absorbtion material. if i can lower something 2-3db, that would be absolutely awesome. The quaife helical geared diff is a no joke when it comes to sound level. I would say even a sequential will have a hard time overpowering the noise level.. We went off track here.. A couple pics of the fitment of the 265/35-18 cr-s on a 10j. Absolutely perfect fitment. The 9.5j is too narrow imo, which is advised by Nankang.

Is not really a surprise.. Try measure the tread width on both tires. You will see that the AR1 is 278mm.. Hardly a 295 tire..

First set of Nankang CR-S to ever hit the road in Denmark. Unlucky for me, the ar1 which was mounted on the car got a puncture. Luckily i had a set of CR-S in stock, so might aswell mount those. Out of the box in damp and cold road, suuuuper sketchy! Noise very low, comparable to Cup2. Feedback is lacking compared to Ar1, but this is based on 100kms driven so far. Lets review that, when i get a chance to scrub in the tires on track.

Sounds good! Alright, that makes good sense, and thank you for elaborating in detail. The digital garage sounds mega!

I like the idea, but are also not entirely sure, what its all about and if the main attraction point are only Buy/Sell/Rent platform and a "facebook" like interface/platform for cars. As i understand, you want to make a database, for the users personal trackcars? (In that case, i guess you also want them to communicate on a platform, like a forum or like twitter/facebook?) Then you also want to showcase where to rent trackcars, around the tracks in EU, probably mainly focusing on Nordschleife for now. But i guess you also thought about users renting their trackcars to others? (i'm not sure how insurance would go with that, if any) And then you want a combined marketplace for both individual and business customers, who can sell/buy cars, parts and similar items for the segment. Is that how i should understand the way you more or less want to go? Because if so, then i would be happy to join too, since it would probably gather more international people together, especially from the EU region. Trackday forum are mainly a german site, but we are a few non germans in here.

Chasing the O.G 1 series cup car. This picture really tells a full story and it has a lot of personal value to me. You see something for the first time, you dream about it, you chase it, you finally got it.. And then you get the opportunity to seal the memory and hang it on the wall.

Aah okay.. Fyi, it only costs 175 eur if you buy directly with Padborg. Including a sandwich and a water. But then 0800-1600 and soft drink+coffee is on top.. But 45 euros arent that much difference.. Do you drive in groups or open as normal? Lets continue in Private, so we don't hijack the thread even more. Sorry everyone.

Who is the organizer? https://padborgpark.dk/vare/padborg-park-trackday-heldags-8-16/ On Padborg homepage it says 25th.. But obviously if you have a german organizer, then i stand corrected. Please send me, what ever info you have.

Nice! I'm not sure if I'm there on that date, because that is the Easter week, and I do plan to go, to the Nürburgring to get the alignment done on the car and start the season from there on.. But in the end, lets see. If I come to Padborg, I'll let you know.. Oh by the way, don't you mean the 25th of March?

Absolutely, i live just about 30 minutes from the track.. I also have a few onboards from 2023 there.

I driven 3 times Nürburgring to Denmark with AR1.. 2100kms total.. Wife drove home the last time, because i got food poisoning..

I drove Nankang NS2R daily for years.. Horrible tire for performance on track, but it last very long and is consistent, but just very slow.. Good on the road if you can live with it being a little sketchy on wet surface and the noise.

Update on the suspension; Last week we received the suspension from Pfeifer. After 4 months of development, sending parts, mainly the rear assembly back and forth between each other for several times, we finally managed to meet our goal. Its not a secret that the manufacture was a litle out of comfortable waters, but that goes for our side too. Both parties had to learn something new. From start to finish; We reached out to pfeifer and explained what we wanted, what we currently was looking at from the competiters. We had some wishes to what we wanted, because knowing from experience that an off the shelve suspension won't fit the cup cars body and the direction we are going with the car. You could go directly and buy a racing suspension. But then the prices are also in a different league and that does not come without issues either. Hence why a guy i know, sent his car directly to KW, for them to develop the exact suspension for his car. You don't get that for baby money. So to make it very simple, we wanted a rear suspension very close to the racing suspension, a true coilover setup. Because down the road, we can then throw the stock lower control arm into the bin and use the one from the cup car, to have the rearend fully uniball setup. This bought some problems into play though; The top mount would extend the full suspension about 30mm, so that meant, when the damperbodies had the exact same overall length as the KW clubsport suspension, it would lose 30mm of suspension travel. So after mounting one side, we lowered the car, took the car out in the driveway to turn it around, and then we realised that the suspension was riding directly on the bumpstop. OK, now what.. So a message to pfeifer, and then after some discussion, they advised, to use a topmount who was a little shorter, and then we could cut the pistontravel down by 25mm. So instead of having a total of 150mm bumptravel we ended op with 125mm. We agreed but had a feeling that it wasnt sufficient. Well afterall, they are the experts, so we rolled with their advice. (at this point we still believed they had experience with the m240i cupcar). Just before christmas, we received the 1st revision of the suspension. We did our measurements on the table. Everything looked okay, we was very close to have the same dimension as the racing suspension. But there was a feeling it wasnt going to work, more on that later. On the table, we saw around 7cm's of full bumptravel with the stock bumpstop at full extension. Oh well, easy fix, we removed 16mm of the bumpstops and removed the plastic shim-ring underneeth it. That way, we gained about 20mm extra bumptravel. So ca. 9cms of bumptravel, and now a suspension that was about 40mm shorter than normal CS suspension. Nevertheless, we mounted the suspension. The most amount of bumptravel we had available with this setup, was 22mm but at a rideheight 1cm higher than normal, to make room for cornerweight adjustments. Then we started comparing with the CS damper. Allright, that had 36mm of bumptravel available, and we used 34mm of it. So it was very clear that sub 20mm wasnt going to cut it. Another email, and a long phonecall was done. At this point, it was just a week before Christmas, and we knew nothing was going to be done until after New Year. To make it short, we then told pfeifer exactly what we wanted from the 2nd revision. We wanted this exact damperbody length, we wanted this exact piston travel, and we wanted this exact length of the whole assembly. Our goals was met! And that is absolutely crucial, otherwise the suspension would'nt have been optimal for this car. Through all this, i can only say, that the process was long, but it has been very fair. Both sides, gave their best to make each other happy. And from our side, we are satisfied with the outcome. Yesterday, we went out in the car, a very short drive. But on some very rough country roads, with potholes and rough tarmac. The dampers works really well and fare really compliant. Obviously needs to adjust the settings and have the car aligned again. But out of the box, it feels miles better than the CS 2 way, which wasnt compliant at all.

Just got this in my feed. Absolutely good sounding S55.. And wait... A 8hp conversion with a clutch pedal? These guys are proper tuningheads. If you want to skip all the technical thing, then around the 20min mark is where should skip to.

Me too, i still have about 50% tread left on the AR1. I'm not an official seller or in any form close to that, but as part of my small business i also supply parts for cars. Since i don't have a warehouse i can keep cost a bit down. But this set i have available are at my place though. So there is a relative short lead time on this set.

Crazy looking sidewall too. Almost like a slick.

Nankang CR-S are available also with E marking. Here's some measurements. This set can be sold for 1550eur incl shipping to DE.

That sounds interesting.. Lets see if it wants to pair with a touch screen through that.

No worries, just playing.. Everyone knows that the CR-S isnt a UHP

Some say Nankang CR-S is a UHP tire, because of the 200tw. Source - Nankang.

Yes, you can choose what you want for what you need. Its very cool it is so easy to build for what you need. - No i have not build that extension into it. Because i plan to use a Racebox Mini connected to the Pi through Bluetooth connection and the Racebox Mini have integrated accelerometer, so that should in theory work. But i still have to test everything, before i really know if it works as intended.
