Ive done a little looking around and found tons on tire wear and what to do to decrease it and mixmatch for longer times between pits. But heres one thing I haven't seemed to locate. Any kind of research done on tire limitations vs. power. Obviously traction is a key factor in any race, but the question here is when is it time to go from say an s2 to an s3 tire or a super hard race tire to a soft race tire. What really brings this up is the multitude of races where race tires are not welcome, and needless to say a Cien making 900+hp on street tires just doesnt cut it. Obviously the simple solutions; dont have so much power in a car, easy on the throttle, get a different car..... But still wouldn't it just be nice to know where its really time to switch tires or detune the car some?

Welcome to GTPlanet!
It all depends on the car type. Front wheel drive will handle power much worse than FR or MR. If you have tuned a car then you should keep the handling in line with the power. A stage 4 turbo is also probably a bad idea for circuit racing. You can't handle the power spike on street tires. The only race car that would have tire related grip problems might be the escudo. Any of the other race cars can easily handle power. Just don't go for 1000hp vipers and you should be fine.

Haha no vipers for me. But I have been tuning cars and just trying to find breaking points on the tires. So far its yielded some good aspec points as well as kept some competative driving going. I just restarted the entire game probably 20 minutes ago and am on an sc300 with the s3's. Right around 320bhp and so far so fine. Little issue with tire spin in 1st and real low second obviously because that's where it produces the most torque. But I believe a fc trans and some longer 1st and 2nd gears could be the solver to the puzzle and possibly a little lsd action for rwd's.

Don't be buying a fc tranny for a 300hp sc300, especially after starting the game. Use the 10k to buy a stage 2 turbo or stage 1 turbo with stage 1 weight removal and maybe a clutch. Any fast car will spin its tires in lower gears. If you don't already, use the analog sticks for steering and throttle/brake. Much better control that way. Your car should be able to handle 500hp with soft sports tires.
If you are having trouble with throttle control take an s13 silvia to moorland and run some laps with economy tires. Insanely fun.

Money isn't the issue. I ran the rally to get the rsc already so that's what's paying for it. Heck I just picked up like 4 cars haha. I'm just trying to push the envelope and go out of the norm. For the actual track racing I'm trying to keep wheelspin to a minimum as much as possible.
Just ran a few races with the spec c subby on s3's. Car had no problem at all after 1st gear with slippage. Grip was just fine even in low speed corners. Right around 400bhp. Pretty good I'd say.
If anyone has any lap times with multiple power ranges in the same car and same tires please post as it will be helpful to my own research.
So far I'm finding being a little lower power to actually be beneficial. The decrease in tire spin has neted on average 1 to 1.5 seconds per lap vs the same car with another 30 to 50 bhp spinning tires in 2nd. And this has all be done on 2 cars with factory suspension. Results with tuned suspension I'm guessing will be even greater and possibly be able to hold more power before crossing the line of spinning and not which in turn should improve lap times even more. Also exit speeds from corners have come up between 5 and 17 mph.

I have found that, with high powered cars on street tires, it's usually beneficial to go ahead and use a low TCS setting (1 to 3 depending). However, some guys' idea of fun is something like a TVR Speed 12 on N2 tires.
A word to the wise: Multiple posts are strongly frowned upon here. Better to edit a post instead of creating a new one when you've made the last post in a thread.

Lsd would definitely fix the problem for the most part. But at the same time a high lsd will do basically the same thing as tcs and in turn slow the car down unless very finely tuned even so probably still slowing it down a bit. The last car I used last night was the spec c cubby and with factory suspension and factory vcd (yes sti's have it) I was still getting pretty bad understeer upon hard throttle out of corners. I have since then put in a race suspension and tuned it back to the same settings as my previous spec c just lower power and lower grade tires so we will see if it helped any.
So using an lsd; the logic behind an lsd is that when one wheel slips it puts power to the other wheel(s) to get traction back at the one slipping. So in theory on an awd if the front is slipping setting the front lsd up higher than the rear should put the power to the back wheels and therefore cause more oversteer as a side effect if set correctly.
Just did 2 runs. One with lsd one without. Same track same car. And as I figured the lsd slowed the car down. 7 tenths of a second off my fastest lap. But to the lsd's defense it did make the carhandle noticeably better in regards to the understeer upon heavy throttle out of corners. I'm going to try and dial it in and see if I can't get just enough lsd to stop slippage but keep good times up. Aslo considerably more front tire wear using the lsd with the front tires.
Just did another set of runs one lsd one no lsd. This time the lsd was a little more dialed in and not semi set like last time. I saw almost a full second lap time decrease using the lsd. Went from 1'24.044 to 1'23.163.
