so do these a-arms improve the steering geometry at all? such as improving roll center, bump steer, keepin more of the tire square on the road while turning? i got a friend thats dumpin sum big cash into his suspension, and the company he's dealin with says he'll run circles around me on the back roads. i got sum hotchkin 35/22 hollow sway bars on the way. and all ready got there rear LCAs and track bar in. also agx shocks with 525/325 spring rates installed. SO.... are these arms goin to make a big differnece or are they just for looks?

no they won't change the suspension geometry. I had a set of the BMRs that had the shock mount bend with general road driving. Ended up selling them to a drag racer that reinforced them (I mention BMR because the design is similar).
In the end I bought some stock arms and had some spherical bearings welded in.

When you use our A Arms by UMI Performance and a aftermarket K member. You just cut over 30lbs in weight off the front of the vehicle. So in performance wise yes that is a big difference over stock. Sorry for any inconvenience I just wanted to throw that out there for you. If you have any other questions feel free to ask.
Thanks

yea i read about the weight savings, n thats cool. but im lookin for more of a corner carver. so thanks for the info brad and if it turns in to sumthing im lookin to pull the nose off the ground with, i'll call yea. it was just by budy got this killer a-arm spidle set up for his G-body that changed everything around. and made the thing uber nasty.
V7guy i like that idea? did u use like johny joint or a heim? was it just for the rear rubber verticle mount? or both? any pics? thats more my style build it instead of buy it.

Well yea for the Older G and F bodies there is so much out there to upgrade that design. Now our cars have a short/long arm front suspension. It does very well for road courses. I used to run an after market K member and lower A arms-Not UMIs- and thank god I have experiance behind the wheel or it would have been a nasty experiance. UMIs lower A arms are different than BMRs from what Ive seen. They do offer a twin tube K-member. But only reason I saw needing one is if I needed extra clearance for turbos. Search for LGs A arms. He stopped making them a few years ago. They were very nice.

I haven't had and problems with mine running 625 lb.in. spring rates, but I've got the Chrome Moly version.

Idk just an idea.. http://www.globalwest.net/1993-02_Ca...bular_arms.htm
IMO, not worth it unless you just need to have more +caster and -camber at stock ride height. Why, because you'll lose suspension compression travel using upper A-arms like that.
Just upgrade the bushing in the factory upper arms, GW makes a kit for that also.
