Blown Motor, Engine Rebuild/Replacement.

That's a pretty significant staggering. I go up to 265 or even 275 (and down to 35 profile) in the front when I run 305s on the rear. Stock sport wheels.

too much stagger

What are your front and rear wheel widths and the type of tire are you running? Too much sidewall on a softer compound will cause the issues you're describing.

COSMO · 09-18-2014, 07:11 AM

Thats what I was thinking too. Maybe the sidewall difference is causing the car to float in the rear.

COSMO · 09-18-2014, 09:15 AM

All Hankok v12's, Front 245/40/19, Rear 305/30/19, 35 psi

IMO, I got tired of the V12s. They're good for the money, but the sidewall is too soft, grip gets worse as it wears down, and it doesn't last that long. For just a little more I'm super happy with the Continental DW. I think 305s are available now. My current setup is 265/35 and 285/35.

[EDIT] 305/30!!!

Man, I love me some Continental ExtremeContact DW tires. So far, they are easily my favorites. Excellent value and great grip wet or dry.

Hotrodz · 09-18-2014, 02:49 PM

Yup, I have SO-4s in 305 and 265 and they have been good as well. These and Conti's are much better than the V12 from all the reviews I have read and folks I have talk to.

Z&I · 09-18-2014, 04:46 PM

hmmmm ... my ps2's don't seem so bad now !
245/40/ ZR 19's in the front and 285/35/ ZR 19's in the back.
Very little to No tire squirm under load.

No joke... 2 years, and there's still plenty of tread. For the front, the inside is wearing out and making a little noise, but I've got no problems. The V12s barely lasted a year, and that's probably because it spun out so easily as it started to wear down. I think I'll replace the tires next year.

BTW, I had to adjust a bit going from 305 to 285. It felt a bit weird, as if the car would sometimes want to jump sideways on the freeway. Maybe my suspension isn't setup right [shrugs].

always been a RE-11 fan for daily driving. DW sidewalls are like marshmallows, the car will ride like a benz. NT01 or R888 for HPDE or hot summers are fun too.

check alignment, you may be suffering from a little bit of bump steer.

bacalhau16 · 09-19-2014, 10:11 PM

When I first installed my V12's on the rear, I had my stock bridgestones on the front. The car would float in the rear and "crabwalk" when shifting aggressively. Now that I have v12's on all 4 corners, the car is great. I hope these last longer then a year though. :|

COSMO · 09-26-2014, 02:33 PM

Just wanted to give an update. So far so good, it feels like the motor is getting a bit smoother every time I drive it. Planning on doing another oil change sometime next week just to see how much build up the magnetic oil drain plug has on it..

Are you sending Blackstone Labs a sample after you get the break-in done?
