? Difference in 255's to a 275's up front ?

[6carmello8]

Anyone have first hand experience with this upgrade?

I'll mostly be on the street but the car will be driving very spiritedly

I just learned that with the Ridetech Tru Turns, you can run 275's on a stock subframe! Game changer for those that don't think it's necessary to go with an aftermarket subframe.

Right now, the front is set up with GW arms, and Qa-1's and Hotchkis swaybars. I have a Lq9 /LSX.

Thanks and really any input will help so I can get an idea.

20mm or almost 1". But overall width will vary between mfg's

I was asking more about the difference in the sense of handling, feel and performance rather than a literal difference hence the reason I listed suspension and engine (lq9 iron block weight about 88 lbs more than aluminum etc.)

Wider is always better. If your running 335 out back it will have less of a push (under steer) in the corners.

A 275 on a 9.5-10.0" wide wheel is a good fit. More front end grip and more fun! It should still drive nice down the freeway without much tramlining in the ruts.

Makes sense and more balanced feel I assume. Thanks!

I'm thinking more on the 9.5 wheel for the street with the 275's. What do you think? It'll be negligible but less wheel = less unsprung weight, and the tire will have less "stretch" if any and more "squish" on the tire. What backspace would be ideal? Ridetech recommends 18x10 with 5.75" offset so with a 18x9.5 a 5.5"?
