As an early Christmans present to myself I've got a 1 piece aluminum on the way. Given my mods in my sig, what can I expect in the seat of the pants performance? I've read some posts but just want some freash input.

I did mine and didnt really notice a big diffrence, definety a good upgrade, considering the stock 2 peice is like 45lbs, great way to get back a few hp lost in the drivtrain

spydershaft should be worth a couple tenths and no clunking

I couldnt tell a difference in performance by the seat of my pants, but I went from a 1.86 60' to a 1.81 after installing the spydershaft

I loved mine sfter the install, not really a seat of the pants thing as it was the noise (clunking) going away.

Not to mention you are now safer with the solid

+1 on seat of the pants, but difference in speed.

Finished the install injust under two hours and it would have been much quicker had I bothered to fire up the air compressor.Went with the coast driveline product and install was apiece of cake; installed a BMR drive shaft loop at the same time. Man that stock drive shaft is heavy. Feels heavier than 40lbs because it is "awkard" weight.

Took the car for a test drive andnovibrations to report at 80mph. I can notice adifference in the butt dyno - the carseems to rev faster and pull more from 2500-3000on up.

Something its also never done before isbreak loose (on the crap stockneros) on 1st to 2ndclutch dumps. Tires squealing, not just barking. The clunkyness isGONE.

Man what a big difference!

I put my Shaftmasters on yesterday and felt a definite difference in the car afterwards. It seems to be quicker by the "butt dyno", and is much smoother both on acceleration and while driving. Did a long trip today and still can't believe how much better the car feels - unfortunately they closed the track due to weather once we got there and I didn't get a chance to try it out at the track to see if it has made a difference.
