help with my rim fitment

Post by wilderb » 15 Apr 2009 19:27

I have a 4 door that I am attempting to put some 15x7 wheels with a +38 offset

the front suspension will have 280zx struts shortened for mr2 insert
the rear will have a set of qa1 coilovers shocks that are 15" compressed and 20 1/4" extended
the fenders will get rolled


1. what kind of spacer do I need in order to get the wheels to fit front / back?

2. what is the lowest I can lower the car?

3. will I need flares?

what sized tires?
you will need about 1/2" or more of spacing.
should fit without flares.

Richard is right here, but a 1/2" spacer probably won't be enough to clear the front struts, I run an effective +4mm offset (+14 wheels, 10mm spacer) on the front of my car with 280ZX struts and my tires are still pretty close. I would suggest 1" spacers, and for anything more than 1/4" and I would be looking into getting longer studs. You can see the obvious drawbacks of FWD offset wheels here.

If you are really set on these wheels, with their massive +ve offset, it should be pretty easy to figure out how big a spacer you need by stacking them out with washers or something, pulling your coilover assembly, and then moving the suspension through its whole travel to check clearances. On the front stack washers until the tire doesn't rub on your strut.

You would be better off with the 200sx V6 strut, it has a little more offset of the strut tube in relation to the spindle. you could probably get away with a 5 mm spacer to clear the struts. I have 16x7 +33 on mine with no rubbing the strut tube no spacer either, on the rear I have +38, you will need to grind out a notch in the trailing arm, top and bottom then use a 5mm spacer.

I'm thinking either 205/50/r15 or 195/50/r15 tires

I will also be using arp 100-7708 2.5" long studs so spacers will not be a problem.

I already have 280zx struts as well as thisismatt's bumpsteer spacer and the wheels so getting 200sx v6 struts is not an option, plus they are not vented.

I will try derek's idea and stack washers.

by doing the math if +38 =38mm then a 1"spacer roughly 25mm would give me a +13 wheel, will a +13 wheel work under the stock body?

I run +14 with 10mm spacers up front an none in the back, so effective +4mm up front is fine for stock body cars, and +14 is fine in the back with 195/60-14s, or probably with 205s if you haven't corrected for camber. Like I said, you can test it yourself.
