I got the S-tune suspension and want to follow their recs as close as possible.

They recommend 18's, but do you think that 19's with 245/35/19-F and 275/35/19-R will work just fine with no loss of performance?

Do you think handling will actually increase because of the lower profile?

What about increase in wheel peripheral weight? Will that decrease speed? Or will improvement in handling more than compensate?

Will the TPS work with the above config? Do the above measurements fit within the defined parameters so that ABS, VDC/Traction control, and EBD not be affected?

Thanks.

 

you should be ok, doubtful youll notice any differences. depends on the rims, but often times if your doing forged rims, the metal weighs less then the sidewall of a tire, so an extra inch of rim weighs less than an inch of sidewall.

then you dip into rotational inertia, and its effected by distance from center... blah blah blah. without a lot more info its hard to say exactly how it works out, but its close. suspension shouldnt care what rim is on it as long as the overall weight is similair.

 

ares, we have gone back and forth about this before, and I agree with what you have said.

BTW, I love your signature, Vin would be proud.
