Even though my G35 is a daily driver, I compete in SCCA, FI league. I have a ton of suspension done to my G35, but it is hard to handle because the supercharger is not very efficient for track. Track can come later, as I do not like taking shortcuts and suspension would be alot of money and not fit into my budget. I first need to learn how to drive a AWD before I track the monster .

 

Then don't get springs. Leave it stock and learn it. That's what I did for over a year, then I jumped straight into my race suspension. I took no shortcuts with springs or sway bars.

 

If you want twisties, get coilovers, the MR coilovers are really nice, and really well priced, they are what I will be getting, I would rather spend 700 on MR coilovers than 200 on a decent set of springs that arent going to do much for me.

 

As it's already been said, you aren't going to go wrong with either kit. The thing to really ask yourself is how much lag are you wanting to do deal with? You'd be better off with a turbo with a wider powerband that still has great low end torque if you just want to make 400+ whp.

If you have questions you can send me a PM or ask me here. Glad to help.

The main thing is before you buy ANY turbo upgrade make sure to have the correct other supporting mods.

 

I support Buschur 100%.
