I am new to this forum and this would be my the first questions I have. On my sedan I have 20x8.5 in front and 20x10 rear 275/35 toyo's. I have been putting performance parts on little by little (high flow cats, stillen stage 3 intake, stillen headers, stillen pulley, full stillen exhaust). My problem is car has no traction, when I leave the vdc on it cuts power way too much and when I take vdc off the rears slide through second. What kind of tire setup should I put on? I am trying not to go to an 18. Would a 275/40 19 work in the rear? Also what brand of tire would have the most traction. I was also thinking of finding a rear end out of a g35 sport with posi would that help with my wheel spin. thanks

 

I have 19s with 275/35 tires in the back and don't have a problem hooking up. I don't know why 20s should be that different.

 

You should have more than enough traction with your current wheel/tire setup. Definitely more than stock.
The wider the rim, the more contact patch on the tire, hence better traction...
There must be something else wrong

 

i would think you'd get more spin w/ smaller wheels, no?

 

I was thinking smaller wheel bigger tire more flex to the road

 

I have stock sizes on now (winter) and these tires spin easily. I am running the same size as you in the summer and get great traction. Much more than stock. 275/30 20 Yoko S.Drive. I'm plenty happy with this size. All tread compounds are different.

 

i would probably say its the tires and/or your driving style... What Toyos are you running T1Rs/Proxies 4? i have T1Rs and they grip well... i would not say great though. And its hard to compare because I am on 19's and 19 vs 20 applications of the same tires may be different.

 

tire pressure makes a difference as well.

 

Please clarify.. I am pretty sure that I am not the only to have no clue what you are saying w/ that statement.

We wanna help, but pls HELP us to HELP u!

 

A lot of times you can heat up a tire that large to get sufficient traction.

 

I didnt get one thing you said:

I am trying not to go to an 18. Would a 275/40 19 work in the rear? Also what brand of tire would have the most traction.

I'm putting down 310whp and 242wtq to the wheels and a ew days ago me and friend put some rims on my car to see how they look. I wanted to have some fun. They were 20x9 and 20x10.5 with 275/30/20 and 245/35/20 tires. I was taking 90 degree turns at 30-40mph and they were holding up fine.
And when I wanted to drift i would drift.
It might be from crapy tires, tire pressure, or your car has a problem.

 

WTF... did Stillen have a fire sale or do you get some sort of family discount?

 

well at least my cats weren't from stillen

 

I heard somewhere the rear end in the g35 sport is different and better than the one in the journey is this true?

 

The Sport does have a limited slip differential:

Wiki: A limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
