I just purchased a set front-18x8 ,rear-18x10 of ar rebels with 295s on rear I have done research and I have come to the conclusion that I need 2 in spacers all the way around the car. But I have also read that some people have used less than 2in in the rear like 1.75 spacer. Does anyone have a opinion or input to help me out the backspace is 7 1/8 and offset is 41mm. I have a photo with them just beside my car but can't upload it.

 

You can get away with more backspace considering they are 18's.

With Rebels in 17's, & 5.95" BS, I ran a 9/16" spacer & stock brakes.
This would give you an equivalent with a 1.75" spacer on the front with your backspace.

The rear fit with the full 6" BS & you could get more backspace than me on the front because I was tie rod clearance limited with 17's. You will be limited by the strut to wheel clearance at the top of wheel & whatever you prefer as turning limitations in the front.

You will need at least a 3/4" spacer to get the front hub dust cover to clear the wheel center.


I like the wheels & would love to have a set of 4 in 10"

 

Thanks man I think 2in all the way around what do you think

 

I said above 1.75 or less should get you close.... but there is a flaw in your information. You said 7-1/8" backspace & also 41mm offset. This cannot be true on 2 different width wheels.


I was considering a 7-1/8" BS on the front. The 41mm may apply for the 10" wheel but 41mm on the 8" wheel equates to about 6" backspace.

In that case, considering a small front tire (245mm) you could probably use about a 1" spacer all around, otherwise the 295's will be hitting the fender lips. Shoot for an approx. 5.5-6" BS to keep the fenders off the rear tires under hard cornering. With 6" BS & stock suspension I could get the rear tires to contact the inner fenders when I really hammered the turns. Still better than catching a fender lip & cutting a tire on the outer edge.


Moral of the story is to MEASURE & figure out what works best for you.
You may like them sticking out for looks or inward for function... depends on your tastes & how you want to drive the car.
I went to great pains to keep the tires under the car & modified the inner fenders accordingly.
