Hi,

Cosmic wheels are period accessories.

The GT6 had several ratios - 3.27 and 3.89 included. If you have a higher 
ratio, it is likely out of one of the other Herald derivatives. Spitfires 
had 4.10 gears on some of the earlier cars, for example. However, Andy 
Mace would be the authority on what ratios would be available.

As for your welded diffs allowing any movement, I'm not so sure this is a 
good thing or not. My understanding is that a welded diff is exactly that - 
a welded diff. Put more succinctly, they heat the pumpkin really hot and 
then weld all the spider gears together into one big lump. Thus, there is 
no movement of anything (at least with regard to the spider gears).

For a final say on the matter, show it to a race shop and ask them.

Regarding axles, there's a guy named Wayne Snyder from Grand Rapids, MI who 
runs a Spitfire in E Mod autocross class. He has a 2.5 liter 
Toyota 4AG motor in there - making much more power than a GT6 would 
likely make (assuming you don't have a $25k motor, of course), and it 
turns out that he makes (or has made) special super tough axles for 
Spitfires. A lot of folks run these axles, from what I gather. All 
reports that I've heard is that they are super reliable.

Failing the Wayne S. solution - some folks have modified TR6 axles to 
work with the Spitfire rear. A guy on the Triumphs list who goes by then 
name Barry Schwartz has done this conversion. Seems the V6 Ford engine in 
his Spitfire makes a bit more torque than a stock Spitfire... ;-)

C ya,
