At footbrake I keep the car around 2500RPMs and When a leave brake and WOT the flash stall goes up to 5000RPM. I agree with you. Front end looks like too stiff yet. Looking at your car picture the behavior is so similar then my car... Look at this picture of my car on launching...View attachment 1715127305

Are you using torsion bars? If so, what bars do you have? To me, it looks like the front is sprung a bit too stiff and a shock won't fix that.

If it's a coil over do you know the spring rate and front end weight?
