Brad,
Any chance in the future does UMI have plans for a full auto-cross/road race set of TRUE upper and lower A arms? If you look at 1st & 2nd gen Camaros there are a lot of coil over upper/lower a arm set ups and even entire front clips. Seem to me there's a market for it for 4th gens. What are your thoughts.

Thanks for the great question. Yes. we actually already have coil over set up for road race applications. It just depends on what spring rate you are interested in. Below is a link to show you what I am explaining.

If you have any other questions feel free to ask.
Thanks

With the rod-ends instead of rubber bushing you won't get the constant variation in the geometry you do with the factory rubber bushings, sharper steering turn-in , and better road feel are two benefits i noticed with my UMI lower A-arms on my car. You can get the same effect by changing the stock rubber bushings to GW spherical bearing kit(Part# SP-7), but that's still $310, just $70 less then buying new UMI A-arms.
I haven't had and problems with mine running 625 lb.in. spring rates, but I've got the Chrome Moly version.

The BMR arms made a serious difference in the steering feel of the car. I was VERY disappointed when the shock mount started to fail. i was hesitant to go to a similar design by UMI (even though I've become a big fan after they consulted,built and tested a roadrace K member). the next best thing was the GW kit. I bought used factory a arms, then the GW kit, then mailed it all out to California for install then got them back and installed. I spent more than the BMR or UMI arms when it was all said and done to get something i felt reliable. After all, who wants to loose a coilover while driving down the road or track. I t would be bad on an EPIC scale.
with that said I do run bilstein racing coilover shocks, 650lb springs and a 35mm front swaybar with 4pot brembos and 315s on the front, there is nothing but rod ends or spherical bearings in the front suspension. The BMR arms may have been in unfamiliar territory. The UMI or BMR arms may work great for you even though the design is principally unsound from an engineering perspective.
UMI... any chance you would make a design similar to the LG ones that were so coveted now and years ago? you'd get a lot of good PR from the roadrace guys! lol

i got some tubular upper arms........after taking the stockers off..... i was amazed at how flimsy the stockers are compare to the tubulars.......just as flimsy as the rear panhard.....and we ALL know how crappy the stock PHB is.......you cant go wrong with a set of tubulars
