First has anything been changed like the UCA or LCA's?I just ordered a Spydershaft, im super stoked to get itMy car is lowererd however so I need to ge the pinion angle adjusted. Could someone school me on the how and why about all this? I have no idea about it at all.
no matter what setup you have currently I would install it as is and see how it responds. Most (97%) do not need adjustments but if the suspension has been changed and the pinion angle has been changed as well then you may have to do a little tuning. to adjust pinion angle:
find a spot that it level and jack your car up or use ramps on all four corners so the suspension is weighted. If you are using jack stands then make sure the rear stands are under the axle so the weight of the car compresses the rear springs. this is very important and whatever spot or method you use it must remain consistant on future adjustments.
next you will need a degree finder. Ace hardware has them with a magnetic base which is really helpful.
once you have the new driveshaft installed the new pinion flange gives the ideal spot to check the angle.
to adjust you will turn the adjuster on your UCA to reach the desired setting. shorten to reduce angle and obviously lengthen to increase the pinion angle. It can also be done with adjustable LCA's but it's a bit more complicated since you have top make sure the differential is square so I usually don't advise doing it that way unless you have the experience.
I've found that due to variances in manufacturing and different measuring techniques there is a useful range of +1 to -2.5 degrees.
If you test drive it and everything is fine then leave it alone. These cars are super sensitive to changes in the suspension and driveline and adjustments need to be made in small increments of maybe 1 turn or maybe 1/2 degree on the UCA. It's easy to over correct and cause some frustration trying to backtrack.
If you aren't lowered more than 1.5" you should be okay but it's nice to have the adjustable parts if ever needed or if you decide to drop lower cause you will need it then.
hope this helps a little.
Thanks for the order!

yep. sorry for the delay. I didn't expect to sell so many in such a short period of time and it's got us a little behind but we will catch up fast.Awesome that actually helped alot, I was thinking about getting the adjustable UCA's anyways so I guess that just makes my decision even easier. I cant wait to get the driveshaft its on its way now
GL with the driveshaft install....
just my 2 sense though, i ordered a powerhouse shaft for my car...
my car is lowered too, after adjusting the pinion angle and intensive track testing, i couldn't justify almost 1 mph (.8 to be exact) from a $600+ driveshaft. hell after dyno tuning i picked up way more than that...
needless to say, i was left with a bad taste in my mouth. i didn't notice any seat of the pants difference with the driveshaft. however for my automatic 07 GT with pullies, JMS cai, and axleback running consistant 12.80's @ 106-107 i can't complain after being tuned. stock 3:31 gear too!
