the conversion does result in a very noisy gear rattle sound...at idle(unless clutch pushed in) it is almost embarrassing..when lugging the engine(low rpms,,,ie around corners slow traffic areas ect.) and when starting off in 1st and in 2nd gear just for a bit after the gear shift....that being said I still dont mind since I did a ceramic clutch upgrade...and I can rev higher/faster do to lower mass and dump the clutch at 3500 vs stock 2500rpm dumps...the resulting burnout is unbelivable...(did a custom chip as well..with fans going on at 190f vs the stupid 230f stock)...she burns rubber all the way through 1st...squacks into second and chirps into third....never did she do that b4 that is for sure!!!! I love the performance enhancemant...but I have to say the gear rattle...more of a rut....rut...rut...rut...sound is very annoying to say the least(the rattle is the gears and syncros in the zf truck tranny...now that u dont have a balanced dual mass flywheel) the good news is that dm flywheels do go out and are big $$$(although some bargins on used and rebuildt ones do exist)so doing the conversion does put the stock one on the shelf for the next owner if they ever wanted to go back to the quiet stock arrangement.. All said I love the performance enhancement but hate the noise...typical of life always a tradeoff...My best friend and my pro mechanic and a c5 owner (Big Mike) said no way he could live with it if it were his vette...but then again he would get a lot of static from others(being a shop owner..repair shop)...and everyone would bug him on it... It sounds like a pilot bearing gone bad...and gearheads can't help but notice and comment...LOL so if u can take the ribbing..and have a strong ego(like me)(dont give a crap about what others think..just care abt what I like) then go for it...if u worry abt what others will say or think and give u a hard time abt it..then stay stock...cause belive me they will look, gawk, talk,question, and comment how they could never tolerate this bloody noise then stay with ur stock balanced dual mass flywheel...but if u want a quick revving,,bad-***,,hard pounding gear shifting,,,rubber squeeling ZR-1 then go for it!!! Just IMO but I'll take the Hi-Po ceramic clutch and noisy rut,rut,rut anyday!!!!
