Hi guys I am a new member of the community and a proud owner of an '05 6MT G35 sedan. It has 58k miles. I will give as much detail as possible with the hopes of somebody being able to help me.

I purchased this car from a private party about 2 months ago. The car has had some mods done, including a megan exhaust, a g35 coupe midpipe installation, 18" 2007 staggered g35 rims, and 350z suspension (either shocks or struts or both) installed. the car sits lower than usual so it is obviously lowered. i'll attach some pictures tomorrow.

this is my issue and story:

shortly after i bought the car i noticed that it drifts to the left slightly. the previous owner told me he blew the front left tire and got a cheap crappy goodyear replacement and never had it realigned. so i go the the shop to get an alignment and the guy tells me the struts are damaged and the car is sitting an inch lower on the left side than the right. he tells me i need new struts. i take it in for a second opinion and the people tell me the struts and springs are fine but i need a new front left and right hub assembly. i go to a third opinion (a very reliable and close friend) and am told that the only thing i need to replace is the left and right front hub assembly ($765 with labor) because I have been hearing a whirring noise. So I get that work done and whirring noise is gone, but my drifting to the left issue (especially at high speeds on the highway) of course remains.

The previous owner told me he put on 350z suspension but I barely know any details.

Also, the car does sit lower on the front left side than the right (about 1cm or so) and this bothers me as well. Would getting new struts and springs fix my issues? I'm thinking about getting the d-spec kit from tokico on my credit card. What do you guys think?

Also, I took it to a tire shop and was told the car had negative camber and that was what was causing the drifting problem and not an alignment issue.

If I do this will I need anything else like bushings? And what about coilovers? Would they be better? Are they necessary?

Thanks my fellow G35 owners.

 

I'm not sure if you misunderstood the tech or he's just an idiot, but negative camber IS an alignment issue.

Sounds like you need an alignment, has that been done recently??

 

+1 on the alignment. Also you mentioned that you have 2 different tires up front. Even if they are the same size tire, tire companies do have slight variances in thier sizing, so you might consider getting new front tires that match.

 

^This. A tire from Goodyear could be 1/4" shorter/taller than a same size tire from Hankook. That same variation could easily cause the issue.

Since you have Z springs, you're going to have negative camber. You want negative camber and the car comes aligned from the factory with some negative camber. Negative camber (to a degree) is ideal because in a turn, the negative camber helps plant more contact patch and increase lateral traction. When you drop the car on Z springs, you create more negative camber on all ends. However, you should be right in the correct camber ranges as those specified from the factory for the coupe and Z. Camber in the front is not correctable unless you go with adjustable A-arms. Rear camber is correctable, but I would just leave the camber at all ends at coupe/Z specifications.

Since the car is drifting left, I'd definitely look into the tire differences and consider replacing the two front tires with same brand. Also have the alignment checked, front and rear. The steering angle could be fractionally off. Also, does the car always pull left on every highway you drive? Keep in mind roads, especially highways are crowned in the middle to drain water. Depending on how aggressive the crown is, it will push the car a bit left if you're in the left lane and a bit right if you're in the right lane. Cars with stiffer suspensions and flatter, wider lower profile tires will be more suspectible to the pulling and pushing effects of crowns, ruts, etc. Worn tires will make increase these tramlining effects because there is less tread block squirm and the steering is more direct.

The fact that your car sits 1cm lower on one end is not uncommon. Springs are not uniform in length and weight distrubitions at all four corners is not perfect. These variances can cause fractional static suspension height differences.

I don't know how you could bend a shock on these cars unless you hit some crazy pothole or slide into something. Even then, you would take out a lot in the suspension than just a shock. If anything, you'd blow a shock and a blown shock WILL NOT effect ride height. Springs are what set the ride height and support the weight of the car. Shocks just limit the movement of the springs.
