WRX/Porsche Karmann cabrio 1303

The old 944 CVs were clicking a bit and my plan was to upgrade to 930 CVs anyway. Here are the bits needed for conversion; new stub axles, I already had G50 trans drive-flanges, custom length axles (16 1/4") in 28 spline to match the CVs.


Here are the GKN CVs, I cleaned up the flanges that came with my gearbox but needed an extra pair. After getting up off the floor after being quoted £120 each from Porsche I found some cheaper options from prolinx.


CVs are being 'clocked' as this gives them the best alignment relative to each other, just like you do with a UJ.


All ready to go on the car


And fitted!


Clearance is very tight to the coil-over but is pass-able (this is worst case compression clearance). I spent ages trying to get some smaller motorsport CV boots from GKN only to find that they had stopped making the size I needed!


I've been asked so many times about my cooling system I've finally modified a schematic to show how it is all plumbed up. This system works perfectly, gets up to temperature fast and stays at a constant temperature. The other bonus is that I don't even have to bleed the system from an empty fill as it is completely self bleeding!

Very nice! Where did you get the new 108mm stub axles?
You run a steel trailing arm right?
I am contemplating this mod as well for two years already or longer, but since my old (surely partly or mostly worn) old T2 CV's still hold for some weird reason, I have posponed this conversion still...knock on wood though as Richie says around 500hp, the 100mm's will break...

Love the indexing of the CV's. Never even thought of that. You are a much better mechanic then I am, trust me ;-)

Whats a good source for quality CV's Rich?
