Fox Body Rear Suspension Question?

[Dan Gray]

What are you high HP guy using for rear suspension at the track??

Im running the stock style suspension with tubular controls, stock v8 coils, anti roll bar. I am making alot of HP and it is a stick car. But i seem to be spinning the left rear tire all the time.

Im wondering what everyone is using? coil over? double anti roll bars? whats working for you?

Thanks
Dan

a spool

Strange has a 35,33,31 spline spool and axles with C-clip eliminator kit. That will stop the one tire fire until the pack gets hot with the LDS. QA1 has the 24 way adjustable rear shocks. Try Moroso Trick Springs. I run an 89 Mustang stock suspension style drag car and I am down in the low 9's .20's and .30's. Running a Hoosier 10.5 not a (W) slick, all the strange rear end setup with all QA1 and Lakewood bars. Also when you are at the track make sure you adjust your tires accordingly

OK thanks, ya i have been doing alot of internet surfing about mustang suspensions. Im learning about instant center and center of gravity. I had the lakewood bars years ago, i might have to look into them again.

Thanks

I agree, get a spool. I've always liked southside bars on my cars. You have 90/10's in the front? Car transfering well?

spools gonna suck on the street, get an eaton posi, ive been using my for 3-4 years strong with lots of burnouts and and about 10,000 miles of "spirited" driving and havent had a single problem, still burns both tires like it is new.

As far as suspension goes, if you dont have double adjustable uppers then get a pair, and bring it to a reputable chassis shop and have them scale it and set up the anti-roll bar, if you have an anti-rollbar that isnt properly set up, it will actually make that car worse.

also from the research that I have done another thing to consider is your pinion angle and how it plays a big part in how the car will hook-up. and yes you are making BIG power

Thanks guys

Ya i do drive this car on the street alot so a spool is not really an option. Yes i am running an eaton posi unit for about 3 years now and im very happy with it. Im running drag springs up front with 90/10I talked to a chassis guy yesterday and showed him some videos of my car. He said something is happening with the suspension to unload the left rear. Could be multiple problems. So im just going to let him take a look.

Thanks
