High performance suspension components, combined with spirited
driving, place extra loads on your car's structure.
Flexing of the body structure can in turn lead to suspension geometry changes
which may affect handling.
The JUNTOS strut tower brace features quality design and construction details
which both enhance performance and appearance.

Final
pictures of fitting and the installed product attached, I will be out for a
drive tomorrow, if the weather stays dry, but here is a review of fitting:
Now make your own choice on how to get the strut to "live" with the boot carpet. You could just have one bolt hole each side of carpet, and bolt down on top. But I choose a slit in the carpet, so bolts are under carpet and the strut passes through the carpet. You may have been supplied two long bolts with the strut. Some people I hear did not receive the bolts. I did, however, even though they were longer and the correct diameter. The thread was spaced different to the originals. Hence they would not fit the original nuts. So a quick trip to a local store with one of the original nuts/bolts and you will easily find a match ( the ones I got were labeled 10mm - 1.5 x 50mm, but not sure the labeling was correct on shelves ). Mine cost 48 pence each and I got some spare nuts at the same time.
Now using the new longer bolts, pass these through from inside the boot, with a washer, through the strut and hole in boot floor. Pop the original nut on the underside and tighten up. I used one of the new nuts as a lock nut on the underside. Sort out your carpet and check its tightened down. IF the original nuts come off easy, then its a 60 minute job, real easy--just a socket set and a craft knife required.
