how much would i have to shorten my rear end to run a 18x10.5 wheel with a +20 offset and a back spacing of 6.54

 

I narrowed mine 1" per side and ended up with a +19mm on a 18x11. Should be all math from there...

 

how much did that run you to shorten your rear end??

 

is that the answer though 1"? and how much does it cost to narrow a rear end?

 

May be cheaper to find a 3rd gen rear - theyre around 1.75" shorter per side. No idea what it costs to have one narrowed

 

I was getting a new rear end, so it was part of the package. No idea what it would cost to narrow a stocker.

 

what wheels are you getting? the new XXR 526's? just curious cuz i was looking at that wheel and it has the same specs u listed

 

Yep exactly the wheels are sick

 

The best thing to do is get your wheels and tires you are gonna run, get them under the car where they will set at ride height and measure the distance between the wheels and get it narrowed to that length. The rearend will have to be out from under the car for you to do it like this. Measure from back of LR to back or RR.

Are you narrowing a stock housing? Getting new axles? What else do you plan to do while your putting new wheels on?

 

don't bother with narrowing a stock rear it's really a waste of time and money.

If you are interested I got a new Moser 9" rearend for sale that's
narrowed 2" per side.
