Directly from m7:

"If you are concerned about strut tower mushrooming and looking for improved handing, then the M7 Strut Tower Brace (STB) is the answer. This is the ONLY strut tower brace on the market that features anti-mushrooming technology.

Over and over we've heard the same complaint: the strut towers mushroom after heavy impacts from the shocks and low aspect ratio tires. At first glance the shock towers take on a barely visible convex shape, but if you would compare it to the original sheet metal, you would find the horizontal plane has been moved as much as 3/8" upwards, throwing the suspension out of any possible alignment fix.

The problem will most likely show up as a slight pull either left or right depending on which strut tower is buckled. The end mounting plates of the M7 Strut Tower Brace will solve this problem by sandwiching the sheet metal and shock top plate, creating a homogenous top surface that will not bend, even during hard impacts.

The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers and prevent mushrooming and potentially costly repairs. The top brace improves handling by stiffening up the front end, especially during hard turns. Made of hard anodized aluminum, the M7 Strut Tower brace features a durable black finish that looks great and will not chip or oxidize."

Again, this is a GREAT product and ALTA recommended. Makes a GREAT compliment to your MINI. We also have the last Anniversary Edition in Black Chrome available. Just call! (Priced slightly higher at $329.99)

Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes & ECUs. The strut tower brace's modular design allows easy access to the oil filter or any other accessories that might normally be blocked and require removal of the entire brace.

Please Note:The brace may raise the hood slightly. Minor modification to the hood liner may be necessary (put away the scissors, it's not that involved!). This is easily fixed by "molding" the hood liner around the brace.
