Just to clearify, on the front is 245/40-18. Custom '77 Trans Am with full Vette C5 suspension, reinforced chassis and roll cage. Tremec 6060 trans, Richmond ring and pinion ect, so a car that is very much like a C5 in its caracteristics. These tyres are very nice tyres, very predictable and the breaking modulation is superb. Don't really drive my car in the wet, but the few times it has happened, it's been great. I am putting 950 hp on the crank, so they have to bite when you put your foot into it. Ran PS2s before, very good as well, but these are more performance oriented tyres, so I don't really expect to get a lot of milage. The ride is very nice, not harsh at all and that is something people has complained about the C5. I suspect it's because of the crappy Goodyears they came with from the factory. I put about 3000-5000 miles on this car a year, street, autocross, trackdays ect. Not for drag, but hey, there's other tyres for that. They look great, albeit being new school on a car that is pretty old school. Anything below 50*F, forget it, they are not for that, but that should be expected. Had the experience in the spring. If you are someone who change tyres early in the season or use the car in the cold, fx at night in a cold area, be aware of this. They do not flatspot when parket for longer periods, which is nice. If you like your car, no matter if it's a sportscar or just a nice everyday car, they work very well. Just don't think too much about longevity.
Oh, yeah, they do produce a nice amount of smoke, doing burnouts:-)
