Thanks!
PS is it a big deal (and expensive?) to change rear end gears?
If it's a street car I probably wouldn't recommend the hatches due to noise and whatnot. You probably don't want to cut up your carpet for something a street car shouldn't have to do very often. For a track car they're great. I call still send you a couple of pics if you want.

The rear gear isn't expensive if you have the tools and the know-how about setting the depth on the pinion gear. I do a lot of work on the car myself but gears I send out.

TKO weighs @ 90 lbs

I think a better solution is a mid engine support, although I have not seen this done on a C4

Default ZF transmission

From JWT1603: "If it's a street car I probably wouldn't recommend the hatches due to noise and whatnot. You probably don't want to cut up your carpet for something a street car shouldn't have to do very often. For a track car they're great. I call still send you a couple of pics if you want."

Thanks for the info. I thought maybe the hatch might be hidden by the cup holder or the armrest, but I know what you mean. My car is a convertible so it's noisy enough as it is without cutting a hatch for a (hopefully) one time use.

As always, I appreciate the helpfulness of the people on this forum. This is where I learned that my 2nd gear problems were probably caused by my leaky slave cylinder, which was probably caused by some low paid worker installing the seals backwards on the rebuilt cylinder!!

I'm so tired of messing with the C-beam and the trans weighs a ton compared to most transmissions. And I don't need 6 gears for auto cross and track days.
There was a kit I looked at [ can't find the bloody thing now?] made for the T5 to bolt in, $125.00, but it used the C beam?

Don't take this wrong, but I see Camaro racers spending $2,000 to essentially set up their cars with bars that are essentially doing what C beam seems to do?

Granted the ZF weighs a ton but the steel need to support everything might well add the weight back into the car you save on the light weight transmission?

So, other than ease of removing broken stuff, what's the advantage?
