BFG R1 vs R1S?

[Matt93SE]

Grip level is better than the R1, but I can't say a whole lot else yet..
I bought a set of takeoffs a few months ago and stuck them on the car right before the COTA race.
Had some weird handling issues and was scratching my head when the local BFG guy asked me why I had 3 R1S on the car and one R1 on the right rear. Hmmm might explain why the car was only loose in left turns!

Anyway, I switched back to another full set of R1 and the grip level was less, but not by a huge amount.

Laps times between the R1 and purple crack R6 are 'only' about 0.5sec. The R6 feel much more stable and have more linear breakaway in turns, but the R1 is faster on the straights- I'm guessing due to lower rolling resistance.

Not exactly the answer you were looking for, but yes- the R1S has a noticeable- not not dramatic- increase in grip.

I LOVE the R1S but have not run the R1. I run them on my T4 Mustang and they work wonders. Now the Mustang weighs in at 3450 so its quite heavy for the tires too. I can usually get a race and qualifying session in before I need to replace them. Talking with the engineer's from BFG..there is no need to heat cycle them before using. Just scrub them in for about a lap and then go. They hold up really well and are consistant thru a race. If they start getting too hot..you will know it. Back off for about a lap or so and then right back to it.

How long does an R6 last in relation to that?
I've run a set of R1 for probably 12 hours and easily 15-20 heat cycles, and there's still plenty of rubber left- albeit getting slower..

I run R1 and really like it. They did get a little oily if I over forced them but managed enough hold for me to be satisfied even in the teenagers regarding HC's.

Thought I would resurrect this thread to see if anyone has new results or experiences. I am especially interested in the wear of the R1 vs R1S and if lighter FWD cars have any trouble getting sufficient temperature in the R1.

Been using R1 for several years. Just had my first weekend with R1S. LOVE that tire. Much better grip and easier to drive at the limit than the R1. Took over 1 second off my 1:33 time from last year. Don't know anything about longevity yet.

Thanks Marty. A slammin deal in a set of R1 made it a moot point for now but makes me want to try the S for the next set.

My experience with HooHoos is if you cook them, you have to back off for lat least a half a lap. With the BFg, they come back within3-4 turns. Not to mention they are more resistant to overheating to begin with.
