Danbev07, could you feel it hitting in the shifter?
Nope, the spydershaft seems to be of a smaller diameter around the shifter, and there aren't any signs of rubbing on the driveshaft. Only at the area pictured above.
Danbev07, could you feel it hitting in the shifter?

it's not but it feels like it's in the shifter though. There's plenty of clearance around the shifter cause the shafts are only 3.5" at that point and the only issue with shifters is the saleen short throw adapter (a little block of metal that repositions the shifter linkage down further to allow for shorter throws using a stock ford shifter on manual trans factory saleen cars)
when i first installed mine i had coilovers on it front and rear so i dropped it down in .5" increments until it started rubbing just to see how low i could go. at a drop of 2.5" on a hard launch it rubbed and felt like the shifter was going to shake out of the car.
it didn't make sense to me that it only did it on a hard launch and no other time until i got a good look at the rear UCA bushings. they are soft and like 3" in diameter so they allow the differential to rotate at least 7 or more degrees during launch and given the stock pinion angle of 0 to+2 (at best) the decreasing the tunnel clearance and the installing of a larger shaft with different pivot points (arc through the suspension travel) there's really only one good solution to solve all these issues.
at stock ride height with stock LCA's and UCA it's not an issue and i've never heard of one clearance problem even at 1.5" lowered it's usually not a problem but any lower it's almost a given.... me know... me tried it first
I don't own the company anymore but still i don't want to see you guys bashing up your cars for no reason either. there's a time for a BFH believe me but this ain't it.![]()
yeah thats the easiest way to do it. it should help the car launch better and less wheel hop too.Update!
Got a J&M Adj. UCA. I set it to the recommended starting point per the instructions sent with it, and that's all I was able to complete.
Spyder, when you say "-2*", are you referring to the method of taking the difference between the transmission flange and the rear-end flange to achieve this angle?
V6 lowering springs+stock UCA=rub with any 4" driveshaft and even some 3.5" shafts. correct the suspension geometery that is messed up due to the lowering and problem solved. steeda, BMR, Metco, CHE Lakewood etc. adjustable UCA with the pinion angle set between 0 and -3 degrees will cure it. sold 900 driveshafts when i owned the company and this is the cure ....NOT A HAMMER !!!!!! LOLplease do it correctly. the UCA will also help the car handle, drive and hook up better so it's a win win win situation.
think of it this way...when you lowered the car the front end had to realigned to correct the negative camber to prevent the tires from wearing the inside edge... well now the rear suspension needsto be corrected as well.![]()
