Default How narrow?

I'm getting ready to pull the trigger on a 9" and I have a question. How much can I narrow it, per side, and still retain all of the factory mounting points? I will not need a E-brake, nor will I be using any ABS stuff. The car is a 1999 Camaro.

Thanks.

I went 2 inches narrower per side. I know you can go 3 per side and still retain the e-brake

i can go 3-4 inches per side and keep the stock points. 3 inches is the norm, and beyond that the lca bracket is usually narrowed. i can keep the e-brake cable with most any amount of narrowed. -5 is still possible, but it all depends on the wheel/tire combo as well.

If you go 3 or more do you have to mini tube it?

Thanks for the info and replies. And I "think" I read somewhere, that you can go as much as 3.75" per side and keep all of the factory mounting points... Namely the lower control arm mounting points and the spring perches... Does anyone know for sure if this is true? I know I will have to mini tub it and lose the e-brake but again, that does not matter to me. I just want to be able to run a 10" rim, with 5" back spacing. So... Will I have LCA clearance problems? There was a company, Billngsley, I think it was, that made offset spacers to help with clearance issues... But I think they are no longer in business. Maybe someone on here knows something about that???

I was about to ask the same question of you guys. I wanted to know how much you guys narrow your 9"s in order to tuck 315/60 MT drag radials and what backspacing you use. Yes, mini-tubbed.

I am narrowed 2 inches per side and I am running a 15x10 on a 5.5BS wheel running a 26x11.5 MT right now and I only had to roll the fender lip. Also if you go 3 inches narrowed you will need to run a 4.5"BS I only lost my E-brake because I went with drag brakes that don't have an e-brake. Hope this helps

Thanks for the info. I'm going to try and go 3.5" per side with a 10" rim and 5"BS and see how it works out. I'll post the results when I do so others will have the information.

I believe you need to go 4" backspacing on a 10 inch rim?? I'm no expert though.

Well if you do that your wheels the outside of your wheel will be set in 1" compared to most cars. And at that point I am sure you will be cutting stuff out of your inner fenders or mini tubing. If you run 3.5" narrowed and run a 4"BS then you can do that with NO mini tub and save a TON of work.

Tucked in a little bit is OK... It will also allow me to lower the rear of the car a little if I want to. I understand that I'll have to mini tube it but that's OK. And again, thanks for all the tips... This is the kinda info I need right now.
