if i'm getting new wheels for my fd because i am getting a wide body kit, (lets say 30mm wider), can i just minus 30mm from what a normal rx7 rim would be?
so say if a normal rim for an fd, say 19x9.5 and 19x10.5 has like a 35mm offset, is it safe to say that my rims would fit good if i just ordered the new rims with a 5mm offset, thereby pushing the wheel out the extra amount the fender comes out? now i'm not too concerned about the whole "wheel bearing" thing, and making sure it is exactly like stock. i am definitely going to drive the car on the street, and all that, but i don't think i'll ever get a chance to really track the car. besides once or twice at the quarter track.... anyway, the shop i'm getting the wheels from says this should be fine, and the guy who is ordering it knows the guys at mackin industries (rayswheels, volk) and stuff. plus the shop mostley deals with high end rims (volk, lowenhart, racing hart, dazz etc...) and i think they know what they are doing... just wanted to make sure!!! harrison |
You're all over the place man, first you need to decide what sizes you wanna go with on the widebody AND the rims.
You need to be specific in order to get an accurate answer. |
ok, gonna go with 19.9.5 up front, and 19x10.5 in the rear. the wide body is 30mm wider than stock.
so can i just look up the offset for a 19x9.5 in front and 19x10.5 in rear for a stock fd, and them minus 30mm? |
I'd like to know about this too - and what long-term effects lower offsets will have on the lugs and others parts of the car.
|
Well I can give you this info. about my car. the front fenders are stock, the rear are 30mm wider. my wheels sit 10mm from the outside of the fenders, they are 18x9 and 18x10 both +45
Hope that helps |
Wheel width should dictate the offset, If an 8" wide wheel has a 40mm offset then a 10" wide wheel should be closer to 50mm offset. To fill the fender wells you may have to use spacers or have the mounting face machined to acquire the look you want, although when you start changing things like this it affects the engineered suspension geometry so make sure you do your homework.

To fill the wheel wells you need a wider wheel.

The fender will be 30mm wider than stock. The WHEEL at 10.5" will be 50.8mm wider overall. If the OFFSET remains identical to the SSR's, there's 25.4mm more width per each half of the wheel. SO, If you're trying for a wheel that'll take up the 30MM gap and are 10.5 Inches wide, you'll need to have a 4.6mm lower offset than the base (SSR) number. 50MM (base offset) - 4.6MM (wheel width difference minus max fender width) = ~46-47mm offset. Make sense? |
Also, a 10.5 +50 should have a 3-4" lip, or more, depending on the wheel..
10.5"x25.4= 266.7mm (wheel width) 266.7mm / 2= 133.35mm (wheel centerline) 133.5 - 50= 83.35mm -or- 3.28" (Front spacing) So lip would be 3.28" if the spoke face (front) lined up with the mounting face (rear). |
