I Have A 69 Nova Ss 12bolt Diff Shocks In Stock Location. From Drum Mounting Surface To First Obstruction Which Is My Shock Is 5 3/4 On D/s And 6in On P/s. I Wanted To Know How Much Is A Safe Distance To Back Off I Was Thinking 5.25 Of Backspace On My Rims I Want To Order. Just Looking For Some Opinions

You should split the difference (since both shock measurements should be equal as the car suspension is mostly symetrical) in your clearance and add an inch for suspension shift under load.

Shocks can be moved inboard and springs can be off-set another 1.5" with kits from DSE and Competition Engineering (to name just a few of the mail order outfits, and all of the chassis shops offer similar kits to start all the way up to a full back half).

As of this miniute i don't want to have to move my shocks or springs inward. I only go to the track a couple times a year. All thats on there now is South Side Machine lift bars maybey cal-tracs soon lol. Just dying for new wheels maybey i should start thinking about the wheel simulator from percy's, just hate to pay $90 bucks for one time use

Just wanted to know what the norm for backspacing is on front wheels not looking too rum a real wide tire up front

In The Rims I Want The Smallest I Can Go Is 15x6 What's A Good Backspacing That Won't Make Skinnies Look Stupid

If you want to run 15X6 wheels in the front you could go with 3" B.S. this way you would have zero offset .15X8 with 4" B.S. also with zero offset , would fit no problem in the rear.

there ias a free visualizer here -http://www.newstalgiawheel.com/wheel_visualizer.asp

I'm going with 15x8 with 5 1/4 bs in the rear now it's the fronts giving me a hard time just want some contrast between the two. So it's 15x6 up front just have to decide on bs can't wait till this process is over lol
