I will let you know when they are both on the lift at the shop side by side.
I will document a bunch of the differences, more so I can put the blue one back together like the gsx will come apart… but it will be a good comparison.
The spyder stock probably isnt as stiff as a coupe, even with the added support from the factory. But with the goals in mind, the chassis will be getting a healthy dose of 1.75" .118 tubing so it can make hundreds of passes legally to hopefully reach the goals.
A nice gsx with 350awhp and good suspension, cage, subframe connectors, etc would make a fun ass cheap track car too for autox, hillclimb, road, etc. I bet.
