hahah, I am hating on that turbo setup.. I'm not committed to cutting into my rear quarters just yet but don't worry bud, My build thread will start seeing some more updates here real soon..

 

Is horsepower the deciding factor on 245/10" over 225/9"? Is there a point where you are better able to use the bigger tire?

 

Kinda. Also tire clearance. Personally, I wouldn't bother shoehorning the 245's onto 9's long term either.

I'd stick with 225's on 9's for road course use up to about 200whp. For autocross though, contact patch is king regardless of hp.

 

do you think this compound would be soft enough/heat up quickly enough for autoX

 

Thanks E!!

 

Where do the RC-1's get shipped from? I'd like to avoid them freezing during transit with crafty order timing rather than waiting until April.

 

California...I think mine were from SLO.

 

Richard mine came out of CA.

 

Mine came from Georgia.

 

i know they have a distribution point in GA.

 

245's, but I got a set of the prototype sets from before they added a smidge more width to the final version - still, ~1/4" wider than the 225 when you put them side by side. You guys with production sets will have a little less stretch on the 15x10:

 

So, after 3 months (28 sessions + some street driving), I've corded the RC-1s. This is on the Red car going pretty hard.

All 4 tires started showing a bit if chunking at the edges at the end of the same session! A testament to my uncanny ability to keep my wear even with expert rotations and tire pressure adjustments (if I do say so myself LOL). After I noticed the chunking, went out for one more session and came back with a badly corded right front tire (driving CCW today). Even with the cording, the tire still gripped. When I came in from that last session, I was surprised by the tire's appearance because it felt much better than it looked. Laptimes over the last 3 months have been really consistent, either the tires didn't fall off or I improved enough as a driver to mask the degradation.

So, how does that sound? I "think" that's really good durability, but this is my first set of R-comps, so I don't have a good frame of reference.

 

How many hours of run time?

 

28 sessions sounds freaking outstanding to me but I'm a noob.

 

12 hours. It was a mixture of member days (where a session is no-kidding 30 minutes) and HPDE (shorter sessions, typically 20 minutes). Range of temperatures too, from 40s to above 80.

 

12 hours doesn't seem that amazing to me (obviously it's good), but 28 heat cycles does sound like a lot.

I've been very spoiled with tires in the past...I don't think I've ever run one set (pair?) of tires that many heat cycles, but I've definitely done more than 12 hours of run time on BFG R1 tires, including enduro stints.

 

My car could certainly use more camber (maxxed out with ~2.5 up front). The outer 1/3 is what wore. Still a lot of meat inboard of that. I'm going to stiffen the sways with the next set -- but I think offset bushings are where I'm headed.

Forgot to mention . . . the "Session of Death" was when I gave my daughter's boyfriend a ride. BIG kid. 6'2" and probably 260-270. Poured him into the car and worked hard to get his butt into the 16" Ultrashield. Enough extra weight to drop laptimes from 1:25s to 1:28s going CCW. Right front worked its little heart out!

 

as someone who sells seats i LOL'ed at the office.

 

I'm curious to know how many time Supermiata driver's tires last...

Anyone willing to share some data even though they we're 205 ?

 

I'm literally so close, phone call with the manager and everything, but still no offer letter so I'm not jynxing it.
