Default r-d cross frame question

hey guys,
i installed the cross frame.BIG difference.i already have the camber brace.with both on the car it makes it so much tighter.no more chassis flex and minimal steering shake on a bump only.i put new khumo escta mx's on the front (had them on the rear),excellent tire.the car feels alot more solid.stays flat in the corners.
the only gripe is the cross frame sits on one of the header tubes on the stainless works long tubes.for a quick fix i put a thick piece of rubber between them to deaden the vibration transfer.i am guessing i can flatten the frame to clear the header for a better long term solution.anyone else run into this and what did you do? thanks,george

I had a similar problem with a 3" exhaust pipe. You can "dimple" the cross-frame with a decent size hammer and it won't hurt anything. This came straight from Dave...when he was running the company.

Does the cross-dram affect the cars ground clearance at all?

You could also shim under one or both front mounting points. I made and installed an 1/8" shim under the LF to cure a minor contact problem with the pipes I had on it at that time.

You'll lose about an inch. I hit mine on only the highest speed bumps.

I have a 87' roadster that we have 3" headers and pipes. Ended up puting about a 1/2" shim under both front mounts and then ended up using a 2x4 and a piece of 1" angle iron put it under the tube and then a floor jack under the front mount of the brace, jacked the car up and this put a little bend in it to clear the pipes. Lost about 1" ground clearance and rub some drives. wro87

I'd reccomend denting the frame. if you have access to a hydralic press, lay a 2x4 aross the frame where you need to bend the tubing and press on the wood. That way you'll limit the damage to the powder coat.

Even though I don't own the company any longer, I still like to hear of satisfied customers using products that I designed. I'm glad you can "Feel the Difference".

The R-D Cross-Frame and the SW 2-1/2" collectors co-exist
happily with no contact between components.

My car retains a stock, tallish ride height and the C-F can connect
with curbs & aggressive speed bumps occasionally.

IMO, exceptional care & communication is necessary to ensure that
shops DO NOT hoist by lifting against the C-F. There is a danger
that the SMC footwells will be cracked or worse.

A great product, but additional vigilance is required.

I have the Stainless Works long tubes and the CrossFrame. I dropped the front of the frame about 3/8 of an iinch by shimming the front attach points with some washers. Seems to work OK. You can also flatten the CrossFrame in the area of contact, it wont effect the strength. The X frame members are loaded in tension.
