Here are some pics on how the shock is mounted outside of the frame rail. I'm using Global West UPC's and stock lowers. Wheels are 17x9.5 with 5.5" back space. It rubs frame rail loc-to-loc but not enough to be an issue. Front fender lips will also have to be rolled. Depending on how low you go with the front you may have to take a baseball bat and roll a bit more.

minitub?
 

Thanks for the pics.
How much did you widen the inner tubs? It does not look like a typical mini-tub job.

In order to keep shock mounts outside of frame rails we cut out the existing tub and moved it in 1 9/16" and then filled in the gap.

Hope this helps.

Thanks, that helps a lot. I had been looking to do something similiar, but was not sure if it was possible. Now you have confirmed my ideas.

One last question - What rear shocks are you using?

I use QA-1 single adjustable's all the way around. IMO for the money they cant be beat. I've noticed great improvements just from shock adjustment.

I'd have to say the first time I really noticed how well they worked was at the 341 Challenge. I typically like to run them at the stiffest adjustment up front on the road course but at the 341 challenge there was so much grip from the asphalt/aggregate combination of the roadway that the front end was literally bouncing up and down around the corners. I gradually backed off the settings 2 or 3 clicks each run until I ran smooth around the corners.

Thanks for all the info. I'll plan to do something similiar as my winter project. Several times I have almost pulled the trigger on the DSE minitubs, but always had a problem with the notching the rear subframe thing. Most likely 275's Front and 315's Rear will be a pretty good balance, with minimum modifications to the car.

Let me know how your Rear 315's work out on the track.

no more tire rubbing!!! good to hear

Global West UPC's?
 

One more question: You don't have a problem with your wheels rubbing the Global West UPC's at full lock? My 18x9" wheels w/ 5 1/8" B.S. rub pretty bad on my Heidt's UPC's.

Thanks Vince!!!

No rubbing issues except on frame rails loc-to-loc. 5.5" backspace works best. Is it possible to run a shorter ball joint and not hit UPC?

Are you using a stock height front spindle with the Global West UCA's? Guldstrand Mod?
