Where can I buy a shift kit for a 2007 Grand Prix GXP?

Cheers,

i ran the ZZp shift kit.
baddls1ss has a intense kit. neither kit is hard, just messy and time consuming.

Area, what was in your kit compared to the Intense? Were you happy with the performance?

Thanks.

I bought the zzp kit and didn't like how it looked with just nylon bushings and a filter. So, I bought the intense kit with brass (or something) bushing, new springs and a filter, installed it and like it. I've just heard bad things about nylon bushings, so now I'll sleep better with the brass pieces. They are both somewhat of a pain to install.

I was looking at the kit on the zzp site. It says not recommended for 20" tires, I was wondering why that was. Would there be more stress on the tranny?

Thanks.
ya know, i could break the tires loose on the 2-3 shift on the bottle, and very firm without it. no change after the kit really.
the 1-2 shift was a lot better, a lot faster, but i was also having problems with the shift times and ecm/tcm tune that i had so in short, yes it was a lot better.


the 20's add a lot more stress to the tranny and brakes in general, hence why they don't recommend it. i chose the zzp due to the reputation of having parts that don't blow stuff up
