Just as importantly, good tires can mask bad driving. You will learn more on street tires that slip and slide than R compound tires with better grip. For the guys that have crashed on R compound tires, I would suggest some instructor error is involved. Students shouldn't be running on the ragged edge (at least not with me in the car!!!! :nono: ). If the students are soloing, that is different, especially late in the day when the "red mist" sets in and there is no instructor to rein them in...... :cheers:Nolift911 said:What Redshift said. I would not run R compound tires unless you are expert/instructor level with many track hours under your belt. Yes you will be faster and yes you will be more confident in your abilities along with the car but...
Once those R's lose adhesion you better be skilled like Shuey to save it otherwise you will be in a world of hurt along with your M.
I have seen this first hand at the track from M3, Vettes and S2000. They look great and fast right up to the point of crashing.
Great point! I was in an S4 at Summit Point with an instructor and he was running R compound. He was "showing" me the track and then we went into the carousel and he began showing me the agricultural side of the infield areas, quite a ride and no harm done but...Redshift said:MPSC is less of a compromise than you think, only because it gives no feedback (i.e. squealing) like other tires do. It may have a predictable traction limit, so if you are advanced enough to feel it, the MPSC should work okay for you. You might need to consider adding 2 rear OEM wheels up front to do something like this.
When I say flip, I mean remove the tire and flip it on the rim. I would also start with unshaved. They just get a bit squirmy when hot in the first few events. You just slow down a little if they get that hot.M5ROKIT said:According to the article, optimum operating temps are between 160 and 220.
I have not taken temps on my PS2 after a session so I don't know what I'm at with those. Have any of you taken readings to see if you are in the range?
If not, perhaps the tire won't improve over PS2 as much?
Also, neg 2 to 3 camber is recommended. What is stock and did you guys change the camber at all? My suspension has been lowered so my camber is more negative (?) than stock but I will have the shop measure it when I go in next. When you say "flip" you mean swap rims right?
Overall sounds like the RA1 is a great tire. Oh, one more question! Am I better off starting out with an unshaved tire to see how it progresses or go right to 6/32? If it's my first time on an R maybe it will ease me into the feel?
