strengthening transmission

I drive a 98 RS. I have bought an ACT pro street clutch kit and JUN lightwieght flywheel from COBB. Anyway, Now that my drivetrain has MUCH stiffened shifting( and HOLLY shi*t does the car have more responce) ....The whole thing flexes WAY to much under stress on and off the clutch.......When I Hit the clutch in to switch @ redline in 1st....the entire engine almost drops to the ground....then when I let the clutch back out after switching to 2nd ...no matter how slowly(burning the clutch !) the engine SHIFTS backwards like crazzy.....

Now I consider myself a verry good driver and racer. I revmatch almost perfectly, and even with perfect engine - transmission speed, the drivetrain has WAY too much flex.

I have been thinking of upgrading to STI engine and transmision mounts....does anyone have any experience with these.....will they help ??? what should I do ?

Engine and tranny mounts will greatly reduce the engine moving by almost 75%. At your current state, I bet if you just crank over your motor it would move about 1.5" or so. After the engine mounts, it will only move like .5" or less. The tranny mount I can't honestly say it will help the movement, but it sure does make shifting more positive and direct.
