I think Infinti did a great job designing a suspension that works on the road. They lowered the perception of body roll and made it lively enough to enjoy on a back road. A road car with a track suspension is usually trash to drive. So I'm glad they didn't go there.

I'm not planning on ruining my DD by trying to get it to excel at the track. BUT I can't help but daydream because it does seem like these cars (even in stock form, with brakes/tyres sorted) would be a riot on the track.

You're right regarding the body roll though lol. While its fine on the road...the actual roll at a track would be immense.

With some of what I've found, I think I could nail building a quick V36 in one or 2 revisions.

@10sec suggested that these cars would be fun on track and I made fun of him (because he's dumb), but I think he may be right. Who knows. Maybe one day, I can entice him/be enticed myself to do another "Spec" build using V36's

 

The first year that I bought my car, I took it to an Auto-X event. The car was bone stock.

The following year I did the same Auto-X event, but this time with Eibach sway bars and a GT-Spec FSTB. The car wasn't lowered, and had the same OEM summer tires each year.

The difference was like night & day. OMG the car was flat. If you only ever do one thing to your G37, make it a set of aftermarket sway bars.

 

Oh yeah!

I do have a question.

I couldn't find the torque spec for these bastards in the FSM. Someone on this forum said they weren't listed in the FSM.

Is this true? ....Lol???

They're the 3 bolts that attach the front shock-to-LCA bracket.

By memory...maximum allowable torque for a lubricanted C10.9 M10 bolt is like 40LB-FT. So that's what I used. But it would be nice to have the spec.

 

Makes sense...and good to know.

Maybe I'll take a lap or two in the car if there's a nearby trackday in the spring...and if my wife is willing to drive the car up and hang out for 30 mins while I do said laps.

I will need to buy summer tyres anyway. I'm thinking on the Bridgestone S04 or ADVAN Apex. Also not sure if I'll do 19's or stick with 18's

 

I drive pretty agressively for a "commuter" and I can feel the potential for becoming a seriously quick car. Cornering is a bit lackluster but that could just be the tires that are currently on it. Previous owner put some Firestone Fuel Fighter's on it and they don't have an ounce of performance engineered into them..... I'm eyeballing some Toyo Extenza HPII tires right now for some good performance all seasons with a cool tread pattern, but it just stinks they have such a short milage warranty on them. My work commute just got cut in half so maybe I can pull them off..
Anyway I'll stop rambling. I really do think these v36's can be real performers. As you said they just need a few mods here and there and you've got a real contender. I'm just trying to find the time and the money to put into mine to make it a fun, good looking and performing daily.

 

These cars perform surprisingly well at track days with the right mods. Take a look at my build thread sometime. However, cars have gotten a lot faster since this car came out so even though my car is sitting at 400-ish hp. and has all the mods you need for a good track car, it is simply not comparatively as fast as it used to be. Sure you still surprise some people, but you cannot run at the front of the fast pack anymore.

 

I know what you mean. I started going to the track like 14 or 15 years ago. I was using 240hp back then...and I'm at 240hp today lol.

15 years ago, seeing a Camaro probably meant it was going to hold up traffic. Today, a total gentleman driving a Camaro could outrun me even if I was having a good day.

A stock G37 is significantly faster on a straight than my S2000's are. The G would be a lot of fun at a big track (Road America or ABCC full).

I've seen your thread, BTW. You killin it, bruv.

 

Tyres make a big difference. Ever considered just using a summer tyre and then buying a set of snow tyres?

I find that there aren't any UHP all season tyres that actually work in snow.

 

Spot on about the Teins. I ran the OG Flex’s and then thought it was a smart idea to try the MonoFlexs. Horrendous on the street no matter what I did. Added preload, trimmed bump stops, adjusted dampening, raised height. Rode like crap on anything but perfectly smooth roads.

Basics and Street Advanced units ride surprisingly well though. Along with the Comfort Sports.

 

I know what you mean about the Camaro. The SS 1LE is for real and puts down crazy fast lap times for how much it costs. I gave that car some serious thought for my next ride, but it is so plastic fantastic inside and so tough to see out of. It looks huge outside, but feels like a coffin inside. I sat in an M2 to compare and it is the exact opposite. Looks tiny outside and feels comparatively huge inside.

I only live about an hour from Road America and my G has had a lot of fun there over the years, but could definitely use more power for the long straights. I like Autobahn too, but oddly, this is one of the few cars I have owned that I never brought there.

 

Lol I had to go from 12K/7K down to 7K/4K to make a set of flex work on a different car.

I called the 7K/4K version "comfort flexes". I thought they were fantastic in that orientation because the damper could finally keep up.

Later, someone did some frequency calculations (I had the sprung/estimated unsprung weights for this car) and claimed I was "spot on" with those rates - according to theory - for the "GT" style setup I stumbled into.

Good times, them.

I was hoping to get some of that data and MAYBE even try out some fancy math on the G. But alas...didn't have linear springs to do my backdoor calculations with.

 

Ha! I live about 1hr from ABCC.

Road America (stupidly) was the 1st track I ever went to. In a S2000 I bought 7 days prior to going. Younger me was almost as reckless as today me.

Do you need back seats? M2 is like the same cost as a Cayman S, isn't it? Or a used 996.

 

I do need back seats for my 2 year old daughter. A new M2 Competition starts in the upper $50k/lower$60k range, but used they are going in the mid-40k range right now which is not bad considering they are really only about a year old. I was just reading all the press releases for the new CT4-V Blackwing and trying to convince myself to get on the mailing list. You can read all about those adventures over the last 2+ years in my thread in the sedan forum.

But to get you back on topic ("Hi moderators") did you notice much difference in ride quality with your suspension setup?

 

It was a good learning experience for sure lol lesson learned, suspension systems take work to work correctly.

Also I see you mentioned you noticed a good amount of tramlining after the drop and spacers. Was is it one or the other specifically?

I haven’t installed my 20mm front and 15mm rear spacers yet but I am concerned the added track width will mess with the scrub radius and cause some exaggerated tramlining.

 

The spacers were causing it. I took them off and presto!

It wasn't really tramlining. But have you ever seen a aged brodozer? Like when they hit bumps with their -200 offset wheels and the wheels wobble side to side more than up and down?

Obviously its not that bad with the spacers I had (20mm up front). But from inside the car, hitting expansion gaps sure felt like that haha. The steering wheel got shook side to side and obviously, that shock goes through your forearms and stuff.

It just didn't feel "planted" and solid anymore.
