It looks too tired!
Certainly where the rubber meets the road, only multiplied!

You see mine from the rear with the 345's. :tup:

:iagree:

Also thanks to all the people who helped me out by answering questions and sending me pics to study to see if it was even possible to fit this wide a tire up front.

Small update. One of the most frustrating rules regarding building a car for this class is the one regarding suspension bushings. Due to this rule we cant run nice arms like spl or voodoo and a means we are stuck using arms that are more difficult to work with.

I had a set of z1 arms which don't allow for even or easy adjustment as you have to take apart the front suspension to make any changes.

The z1 arms were durable so I would recommend them to anyone looking for affordable arms if they dont plan on adjusting the car often.

I decided to "make" a set of arms that were easy to adjust but also legal for competition. I started with a set of upper control arms from gk tech. These arms are new on the market but the company makes stuff for the 350z and other Nissan cars.

The control arms from gktech work very similar the spl arms but are like a 3rd of the cost. These arms have spherical inner rod ends but the bearing is a standard type that you can get from most stores that stock suspension parts. What I decided to do was replace the rod ends with a type that would be legal for racing. I was able to find a set of rod ends from a 4wd parts company of all places. The dimension and type were perfect for the 370z. I ended up having to swap over the guts from the bushing on the z1 arms to make the rod ends work but someone might be able to put together a set by just having a set of inner sleeves made for the rod end bushings.

Anyways, now I have a set of arms that are easy to make adjustments on and are legal for racing. The only drawback so far is that they gave up some caster. I haven't measured yet so I can say how much, but it was around +8 with the z1 arms. These seem to be more in the range of the stock upper control arms. They do allow for a much larger range of camber which is very nice. Even with the new rod ends I was able to get around -4 and there seemed to be enough threads left to get even more.

Fyi it seems like it would totally be possible to convert a set of spl arms the way I did these GKTech, I didnt want to spend $1000+ finding this out if I wasn't sure.

Got some shots of the 315 in action.

Great photos, per usual!

Tires look monstrous! I love it!

Did your times and traction improve?

She looks very composed!

Definitely. These tires still hate to get hot so on a long course with two drivers, staying fast from lap to lap is still a challenge. On my own it should be less if an issue

I shot an event at the track this weekend and took a break between run groups to take photos of the car with it's new sexy stance. I'm much happier with how it looks now and it drives well on the street too. I just hope it doesn't push too much. Still not too pretty to send it.

My buddy took photos of the car in action. It's cool to see the suspension working under load. The car is driving well to where I think I can leave it alone and just focus on fixing bad habits with my driving. The new bump stops are doing a good job of limiting the wheel travel to where I don't have to worry about rubbing and they don't make the car push at all which was a big concern. Cant wait to drive this car again.

Seems to be using all the tire even at -4 degrees of camber. I'll need to get out the pyrometer next time we have an event with less downtime and warmer weather.

Would be quite a task to induce under steer with 315 up front tho :rofl2:

I still chuckle with joy seeing the 315’s up front

Nice pictures!

Thanks dude. I suppose it doesn't matter now but my bump stops are active, meaning the car is always on them. If I got the packing wrong the rate would go infinite too soon and make the car push but so far it's pretty great. Feels and looks like dramatically more roll resistance and grip for $15. Most importantly, it goes low and rides good. :yum:

Did you go to Nationals? How'd it go? I see Bill Zerr didn't do as well as he normally does.

This thing is so beautiful yet such a beast!
