I'm thinking of ordering the Kia 4.77 gears and just getting them Cryo treated, is it worth it or should I just buy from Rick's? Also if anyone can reccomend where to get Cryo treatment and cost, and probable cost of install I would appreciate it. One last question is exactly how much will this actually effect a car's 1/4 mile time? I know the S2000 is not a straight line car I'm just having some fun, thank you.

 

bump!
