Hi guys...

I don't have any true track time with my GT6 MK1 just some limited  

But running 480LBS springs up front with Spax shocks, spacers required  
because the springs are so short the bonnet would come crashing down  
on the tires. DSCN1246.JPG

Altered the location on the rear links where the spring connects.  

And then used a 3/4" diff block because the rear was just slightly  
going pos under load. GT6_MK1-4.jpg

I doubt this is very track worthy, but seems to suit my MK1 very well.

I have a set of 13" wheels which I hope to fit some nice rubber to one  
day and see if the results are the same with the 15" wheels.
