Suspension suggestions?


Hello, my g35 coupe is stock height I'm thinking of lowering it about 1" inch or 1" and a half. I'm on a budget and wanted some suggestions.

X the sub-forum you posted in is for suggestions to make the site better so no car questions are allowed there. However I moved your thread to the appropriate place and if you do a search in the Suspension section and read the stickies you'll find more answers to your question than you could read in a week. Welcome to the family and we hope you enjoy your stay.

Lowering just increases your chance of scraping parts, this car won't be raced with, will it?

I have the nismo s-tune suspension on my coupe, 20mm drop compared to stock, 15mm/25mm wheel spacers front/rear. No chassis rubbing but my front fenders are rolled. Scraping/bottoming out is minor as long as you're careful. I have a complete **** path across the construction site to travel every day and don't have any issues. Personally I wouldn't run any lower than that or steep cut parking lot entrance would be a problem, same with tall speed bump.

This is a daily driver, on the highway, through a construction site, so I need to be able to navigate debris. Handles great too btw.

A very mild drop that looks great but is still street able in 95% of situations is an eibach pro kit. Understand, however that if you want to do it properly you'll need new shocks (all around), new front adjistable upper control arms, rear adjustable control arms, eccentric toe bolts and spacers all around (25mmR and 20mmF). It will seem expensive, but if you dont spend the money now you'll be spending morr money later on tires every 15k miles.

Better to do it first.

Yes it will be used to race at times.

i would recommend buying the Tein Basis Z suspension if all you are looking for is a mild drop and improved performance. the kit is typically sold for about $500 shipped and will come with properly valved shocks with springs. Buying eibach pro-kit and a set of good dampers such as Koni Yellows will be a lot more expensive and not significantly better if you don't know how to tune your damper settings. I have a thread reviewing this suspension and i talk about alignment as well. with a 1" drop, you can get away with SPC cam bolts in the camber/toe slots to correct the rear alignment, that way you dont burn through tires every 10k miles.

I couldn't have said it better, and have! Without the suspension kit you'll be lucky to get 15K miles out of your front tires, more like 10K! Lowering our rides isn't cheap, be prepared to spend $1200+ to do it right! Wheel spacers aren't required...FYI!

This is true. If you plan on dropping the car any more than an inch or so, be prepared to shell out money for control arms in the front and camber arms in the rear to get your alignment in check.

If you can stay between 1-1.5" like you've stated, you can spend $60 on 2 sets of SPC camber/toe bolts and you'll be good. your front camber should rest at about -1.5 degrees (mine sits at -1.3 with a 1" drop). The alignment shop will zero your front toe with the tie rods.

Rear camber can be corrected with SPC cam bolts to a certain degree. My alignment shop got me to -2.3 degrees which is fine for me, it adds rear stability while driving hard on track.

You will want to ZERO the rear TOE to prevent premature wear. it is a common misconception that tire wear is caused by camber, it is not. toe in is what scrubs off all your rubber and is caused when people lower their cars without getting aligned. Make sure you go get aligned after whatever you do and you'll be fine.

if anything is confusing, don't hesitate to ask. we're all here to help.

Also depends if you actually do much mileage and your driving style, but I wouldn't say you "need" adjustable arms.
I have -2.5 ish camber in front and about -3 ish in the rear, natural from the drop on Tein s tech springs, on stock arms. The tires I run - Pirelli Pzero front/Michelin PSS rear - are pretty soft compared to most and even with some hard driving, cornering and launches I have at least 2/3rd tread depth remaining after about 10,000 miles. The fronts don't actually show any signs of camber wear but the rears show a little. The inner most groove is around 5mm and the outer most is about 6mm. As said above, make sure the toe is in check as bad toe can eat the edges of tires in under a thousand miles.
