QA1 Tubular K Member

So, I want to get this QA1 Tubular K-Member for my 88 Thunderbird, and I was wondering if anyone here has any experience with this piece, and what they think of it. I can't think of any reason why this wouldn't work for a Thunderbird, but I figured i'd check first.

Thanks

Griggs racing says their stuff works on Tbirds, but (as far as I know) they are the only ones who will say that for sure.

85 Thunderbird 30th...#2471, 29k, all original and might actually stay that way

Ok thanks for the info, it's too bad their K-Members are so expensive.

I have a Maximum Motorsports K on by Turbocoupe, had to shim the four main chassis  bolts.  There seems to be a slight difference ibetween the Mustang and the TBird chassisin this area.

OK, so how about some experience with the QA1 model? (the one I'm considering using as well)

*should*.. but when do things ever work like they *should*?

Until that Murphy guy crams his law up his arse, anyway.

Well,,, all the k members are made to fit a mustang so they all SHOULD :giggle:  have the same design... But I guess it depends on what year mustang they fitted it too.

I had a problem with the maximum motorsports k member on my 87 cougar, all the bolt holes lined up perfectly but I needed a 3/4 inch spacer to make it fit. Now...Johns331 only had to shim the bolt holes to get the same k member to work on his TC. :dunno:

OK, that just sorta proved my point.. :D but what I'm more concerned with is differences in quality, etc. QA1 is the one I see every time I'm browsing the Summit catalog.. (good bathroom reading.. lol) so that's the one I'm most interested in reading more about, in that department.

I had to use about ¼" in spacers to make it fit. Some of the differences between the Mustang and various years of the TBird/Cougar has to do with how much anti dive is designed into the front suspension, and what K member was originally  installed. I'm almost positive I took out some of the anti dive when I installed the MM K member, as the suspension is much more complaint in braking.  (high anti dive percentages tend to lock up the front suspension under heavy braking)

I plan on installing a tubular k-member on my 84.  The 3/4" spacer you are talking about is that between the k-member and the frame?  Also I plan on using the tubular A-arms and coil over shocks hopefully the mustang ones work

You get what you pay for...

I wouldn't trust my ass to a $250 K-member............
