I have the DDM race intake so no upper strut bar will fit or am I wrong? Which underbody brace has anyone installed and been running? M7 ones don't list for R55.

 

Actually, there is an under strut system for the R5x platform:

Fits the R55, R56, R57, R58 and R59 as listed on M7's website.

big thank you. Saved me lots of time.

 

check out our TSW X brace it bolts right on no drilling required, can be installed in 10 min or less. The X design is by far the best as it crosses the open area of the subframe to do the most stiffening possible.

Ok, Way. Save some money with yours. Any sale coming?

 

They have free shipping right now

 

The GTSPEC upper strut bar works with the DDM race intake. I also use the TSW XBrace, The car is so tight now.

 

Shoot, just brought the strut plates from ECS. I would have gotten the GTSPEC front bar instead. Will get the TSW WMW X bar in the next step.

 

Anybody try the Wiechers Sport lower
chassis brace (ECS Tuning)?
Looks a bit like the TSW X-brace
(which has had good reviews but is
currently unavailable), but slightly
different and unfortunately pricier
than the TSW.
The M7 USS and the MARS bars
don't look like they'd be nearly as
effective as either of these two.

 

I too would be curious. I was just about ready to pull the trigger on the TSW brace, when it went out of stock...

Here is the Wiechers part in questions:

Wiechers has good stuff they do the braces for the MINI race cars in Germany and roll cages.

 

Do you know how much it hangs down from the chassis? - what is the reduction in ground clearance?
Any pics of it installed and/or showing the mounting points?

 

Decided to go ahead and order the Wiecher lower brace.
It'll take about a month to get here.

 

I am anxiously waiting for your review with pictures...
