They are fullout summer tires, but do quite well in the rain. I've used them in snow/ice, but wouldn't recommend it. They have a much higher wear rating (380) and less actual tread than most other tires which results in them being much lighter while still lasting well. I normally get 15-20k out of my fronts and 40k+ out of rears if I don't swap them.

My 18s are right at 18lbs each, the 350z track editions are forged rays! (but they are only 18x8)

Going lighter weight on rotational mass is a great way to reduce drive train loss and increase power. I've seen dynos change 10+ whp between lightweight forged 19s with meaty tires and lightweight 16s with light DRs.

The sidewalls on the exclaims are soft, but not "thin." I've gone through many sets with no premature failures other than caused by nails. When at lower pressures (25-28psi), these tires will absorb more drivetrain shock and get better traction due to the sidewalls flexing. This is also bad for the autocross type because they will squirm some under hard braking and are a bit slow on turnin. However, in straight line acceleration, they work great.

DRs grip far, far better than street tires. In the 225/50 size, I get the correct height for my gearing and around 8.5" of tread width. If I went to a bigger size (available from hoosier), I would be going up in height, weight, and frictional loss without a big gain in traction. They already hook solid on a 6k launch. There are civics out there running 10s on these exact same tires!

That run was done with I/H/E and a tune (UTEC) on a stock clutch that was near the end of its life. Just to contrast, the 1/8th mile on that run was 8.613@84.52 on a 0 DA and I've more recently done some 8.2s@85s in a 1800 DA.

Aman - yea the 3G wheels are still pretty heavy, I think about 24-26 pounds.

Thanks.

My quad ATLP V2 is en route here. Let's see what this will do.
P2R TB spacers and engine torque damper also on it's way.

Hmm going to do master slave cylinder they said this improve a lot on high rpm shifting.

Certainly! Sonnick was telling me about the delay in shifts because of the stock slave cylinder and I can tell ya for sure that I gain a solid 2mph at the track just shifting very fast (or power shifting) vs more "normal" fast shifting.

they are lighter than my 16inch 1999 wheels by 5 lbs. the 3g wheels weigh 23 lbs
