Hello all,

New Member. First Post

I have my first real project car. I bought a 2013 G37s and have recently begun to mod it.

There are a few amatuer race events around and my intent is to end up at some of them.

Now I understand the effects of lowering the car. However as this car already sits pretty low (I am a big guy though so I may just be misjudging it, 6' 3" 220)is lowering it more really that necessary? Will I see that noticeable of an improvment or can I supplement the suspension or modify it to get the same effect? May be a silly question
but it's my first project and I want to do it right lol appreciate all the tips I can get! Thanks!DOMO

 

If you got the s model your suspension won't feel much different, sport version already has stiff springs, I would recommend a mild drop. Eibach are really popular and mild not too low so you don't scrape everywhere, I have them myself but you its recommended to get at least a rear camber/toe kit so you don't toast the tires. Anyways just my opinion congrats on the car! You'll see a lot of threads regarding lowering springs and definitely gives it a nice look and then if you ever want aftermarket wheels it's looks amazing! Good luck with your build

 

If you want to really make your G the best for spirited hard driving I'd invest in really good summer tires, upgrade your sway bars, and get better dampers from Koni, or coilovers such as KWs. No need to lower it for it to handle well under high speeds, but bolstering the body roll and a more controlled damper will really help. Eventually brake pads w/ better bite should be on your shopping list.
Your stock Bridgestone Potenza tires have good grip but don't wear well and are expensive to replace. When the time comes look into some Michelin Pilot Super Sports if you have the budget, there are cheaper options too that will perform better than the Potenzas.
For brake pads the Stoptech Street pads work well but dust more than OEMs.
Hotchkiss sway bars are a very good upgrade too.

 

Koni yellows + your spring of choice

 

Lowering springs are mostly for looks, however you will see a slight improvement in handling. If you go with Eibachs you may not need the rear camber kits. I wrote a review in the review section, and posted my alignment specs. Have fun with your car and good luck.

 

Very awesome information guys I appreciate all the help!
Yah Ricio it is the S model though and in all honesty the lowered G looks good but I wanted to keep it as stock looking as possible mostly because of how much cars get profiled in my town. Thanks though! I love the car and it's been a blast so far getting it tuned and modded. Enkei Aftermarkets are already on my list lol

Any recommendations on a rear camber kit Ricio?

And thank you much newt that's exactly what wondering. I figured a beefed up suspension would do alot. I have looked at the ARK coilover system for the G37 however I'm strictly going on reputation when looking at them. I will check out KWs and definitely put those things you mentioned on my check list. I have Michelin Pilot Sport A/S 3 on it now because from what I read they performed as well as pirelli summer tires and it was winter when I got the car.

 

Thanks Rash. Yah I see alot of people talk about lowering car for performance etc. So you kind of gotta wonder lol that's why I figured it'd be good to ask before I pay a track fee haha I'm going to go check out that review though thanks!

 

Yes depends on the budget for camber kits, SPC has a good set that are affordable and if you want something better SPL is a little more expensive but better quality.

 

If the roads by you are somewhat decent (I see you're in Cali, so snow isn't an issue), then go for it.

You can get some coilovers and keep the height pretty close to stock, and get better handling as well. With a RWD G, your options are pretty much unlimited.

 

If you plan to track the car, invest in a good set of coilovers with dampening if possible.

 

If you want the car to look stock, as in, not stand out as a 'modded racer' in the popo's eyes, look at Swift springs. They also maximize the travel with fewer coils, so you don't pay as much of a compression travel penalty compared to other lowering springs.

But the big difference is the shock. Don't bother with the budget coilovers if you're actually trying to get performance out of the system. They all use pretty cheap shocks. Konis are as good as you need if you're sticking with a street tire. When you switch to R compound race tires, you'll be able to use the extra firmness that a coilover would give you. Otherwise, with a super stiff coilover and street tires, you'll just be overworking your tires. Of the coilovers available, the only ones worth looking at are the KW V3 and the Bilstein PSS10. But Koni with a decent spring (Swift) will get you about 80% there, and you probably won't notice the difference if you're on street tires and if you don't have a lot of experience.

As mentioned, sway bars will control the body roll, and they are a good cheap start. If I were you, I would get a set of Konis and sway bars, an oil cooler, and a radiator, and then just spend your money on seat time with instruction. You have really great tracks around you in NorCal, so there are always track day events happening. Also, the Porsche Club and the BMW Club usually offer discounted track days for members. You could always register and go to those events - they're usually great groups to run with.
