Bone stock 997.2 GT3 3.8 on the stock tires with track alignment, very likely in the 1:53-1:54 range at the Roval. The GT3 RS 3.8 should be in the 1:50 - 1:51 range, as the key for a fast lap at the Roval is the speed through the bowl, and cars with low downforce hurt in here.

My RS had PCCB, monoball upper control arms, monoball toe links, wider than stock tires (265/345 vs. 235/305) on a stickier compound, Carbon GT2 seats, a 20 lbs lighter battery, GT3 Cup front spoiler lip, and a heavy as brick (83 lbs) but body stiffening TC Design Rollbar, hardly a stock car. My fast lap on the MPSC was 1:52.787 and the fast lap on the slicks (same day) was a 1:47.830.

So quit smoking or sniffing whatever you do, because a stock GT3 RS 3.8 on slicks won't do 2:13s on slicks, no matter who drives it. The realistic times start at 2:15 and up (on slicks) and 2:18s and up on shaved fat wide RA1 with a Pro driving.
I'll quit when i'm good and ready. Sticking to my math because it seems to add up?

I pulled in from a session (30 minutes of heat soak) and Ian hoped in the car. In traffic he was doing 2:22 and Traqmate TBL of 2:20

I'll bet Ian in my car, cold weather, no traffic could click off a 2:18.......I would have to buy track insurance to let him try though
2:18, I agree subtracks slicks and we're there again.
Working on good track insurance. Stay tuned.

This means if I add slicks to the car I will do a 2:20? I might be faster, but not 2:20 fast (I still will make same stupid mistakes)

For an intermediate driver yes, but an advanced driver the difference between Hoosier and race shaved RA1 might be a second.
No, you are faster everywhere, mistakes and all, gears higher etc.

If you put slicks on your Beetle, Reter will be history, and you'll be under 2:20s with your driving skills..
So, a pro is much faster then me agreed?
Slicks 5! seconds faster and we are back to my math.

I think our shaved cheater RA1's are much closer to a Hooter at a 2:25 clip in the summer around Sebring

South of 2:20.....hmmm....maybe a set for winterfest just to pick on Erik
It's like crack. Rodger will give you your first set free. Sub 2:20 easy. I will do sub 2:18 easy. Shane Lewis runs 2:15 in a GT3 non RS on slicks with an LSD only. Now, he IS A VERY fast driver, even more so at Sebring, but again, tells me a pr on RS can do a bit better then that..

This is becoming a dead horse until someone hands his car over fully insured. I'm looking into track insurance that will cover a coach :-)

Pretty accurate then. I did 1:53.2 in my bone stock .2. I think a good driver could probably lop off another 1-2 seconds. Your math is good
