Wheel Widths on Coilovers

[skully]

I am looking at new wheels for my 72 and soon to be LS1/T56 transplant and was looking at wheels. Yes, BBK will be installed, most likely the Wilwood.

 

Checking Offset Calculator for differenecs, I was looking at a 9" width wheel with 12 offset that would take me to -1.5" difference. That seems reasonable.

 

So looking at all the posts, what would be the max "Suspension Side Change" a 240Z could handle with coilovers? 2" 2.5"? Anyone know? BTW- I do like a deep dish (lip) look if anyone can point me in the right direction. Seems like the 16x10 steel wheel option is out there too. Thanks.

Measure your car to find out what you can handle for backspacing and width, and the offset will fall into place from there.

4.5-5" of backspacing is common with coilovers.

I have 16x8 +0 with 225/50's, they fit with a very slight roll, so slight that I haven't bothered to do it yet, the rears rub very occasionally on bigger bumps with passengers.

 

I got these before the coilovers, I could have easily gone with nearly an inch more on the inboard side with the same clearance to the fender if I waited 'till after the coils. By coils I mean sectioned struts with sleeves and bilsteins, not the threaded adapters, not sure what the clearance is like with those. If you go with a shorter, stiffer spring you can get the lower perch above the tire and gain even more room.

I have a '71 240z with coilovers and stock wheel wells and I have 17x8 wheels on the front with 245-40 tires and 17x9 rears with 265-40s. I have a custom suspension both front and rear so my offsets probably wouldn't work for you but, if you take time to dial in the correct offsets, I don't see why the same size wheels and tires wouldn't work for you too.
