I'm a noob so please be gentile and detailed in your responses.

I'm looking to put and aftermarket sport suspension on my 05 G35 coupe. As it is, I have a few speed bumps where I have literally a couple of mms of clearance on my factory springs. Are there any good height adjustable suspensions available? Or is there any other alternatives? These bumps are about 3/4 mile away from my work so avoiding them is more hassle then anything, there's no way around them.

I've seen some in the past the rise and lower based on speed... more info would be helpful.

 

most people who do aftermarket suspension do coilover kits, they allow for height adjustability and some allow for adjustable dampening. although most coilovers have an automatic minimum drop when installed. you may want to look into an aftermarket shock/spring setup. For example the tokico D Specs and some tein h tech 350z springs.

 

I think he is asking more for like a Robetura setup where he can raise the car once he gets to a place where he needs more clearance then bring it back down from inside the car.

Exactly. Should have been more clear about that.

 

airbags, but they are pricey.
