I have a solution to the wrong bolt that gtspec supplies with their kit. I also contacted them about the problem and I am getting the same runaround you got. The original bolt is a M11x1.25mm. The bolt supplied is machined wrong. It is a M11 x about 1.15mm. It will start in the hole but will only go in about 2 turns until it tightens up. I am guessing it was made in China.

Get 2 each of the following:
7/16 x 20 TPI Grade 8 bolt 2.5 inches long.
7/16 flat washer with OD about .9 inch.
1/2 x 7/16 reducer 5/8 inch long.

I got the reducers on Ebay. Here is the link of what I bought.

You can thread the bolt in by hand and it does not damage anything. I would also think it is stronger than the supplied bolt. I hope this helps anyone wanting to install this kit in their car. Other than the bolts, it is a nice kit.
