Today I swapped the OEM RFTs for my Z4's RG-Rs and had new PZeros mounted on them. The car rides MUCH better, and doesn't pull to the right any more I guess the RFT's excessive tramlining makes it pull with the road crown much more than the PZeros (which hardly tramline at all)? Anyway, the car feels transformed, etc. etc. This is not news to anyone who has gone from RFTs to "good" tires. The RG-Rs are 18x8.5 and 18x10. Their offsets are stock E86 Z4M. I may add 15mm spacers to the fronts to bring them back to the X3's stock offset. Right now they are a bit more tucked into the fenders.
And I can't stress this point enough...switching from the BMW 19s and RFTs to RG-Rs and PZeros dropped 90.6lbs of rotational unsprung mass from the car! |
