You can buy them here...

McMaster-Carr

or print out the specs and run to a Hardware store that sells Metric Hex Socket Screws.
Just be sure you buy the STAINLESS ones. The key numbers are "M8" & "25 mm" length.

The price you pay at the store may how ever, may make buying the 25/bag at McMaster Carr a better deal.
You could sell the extras to other chatters perhaps!

 

Don't waste your time on a stiffening plate! A simple bolt on piece of aluminum isn't going to do anything for the handling. Stop giving BT Tech money for nothing!

 

And how do you know that without trying it?

 

That's interesting, because it's not what you said before:

So which time were you lying?

And for the record, I have the plate and have been pleasantly surprised by the degree of improvement it has made in my car's handling. I expected less.

 

And of course, you also put on the record that your observation is as good as a double blind test and instrumented measurement, right? Right?

 

Begone, Troll!

EDIT:
By the way, for those who are wondering, the following is what Dobey posted with respect to my consideration of rear stiffening plate to address highway instability in winds.

Then he spent much of the rest of the thread arguing that body rigidity will have no effect on tracking in crosswinds and that folks like myself were just fooling ourselves into believing there was a difference. :crazy: Go figure. Self-consistency isn't his strong point.

In the thread quoted there are quite a few who observed improved handling with the rear plate. As with any other mod, YMMV.

He does seem to have it in for the BT products though...same as mameyer. Interestingly, mameyer contradicted himself in exactly the same way. You just can't make this stuff up folks. ound:
