SCCA STR 370z Progress Thread.... It can be done!

j-rho · 10-08-2014, 04:25 PM

Rear subframe bushings - need to be done? Made a big difference on my 240sx, and Brian talks about them on the 350. I see there are some solid aluminum (illegal) parts out there for the 370, but not the normal delrin stuff?

Got some parts put together - wrenching starts soon

Subscribed. Any insight on your use of Spc vs SPL suspension parts? I'll be installing my Whiteline sway bars shortly.

SPL parts use spherical bearings which are against the rules in Street, Street Touring, and Street Prepared classes.

End links can be spherical in street class. There's no rules on those. However actual suspension like control arms etc cannot use spherical bushings unless it came from Nissan that way. I use SPL end links in street class.

Not sure of the rules but maybe you can install some Craftsquare mirrors to help with visibility on the driver side.

Hey, so... I don't have enough time at the moment to read through your build.

However, I'll share what Ive learned...

You might want softer than 12k rear. The last setup I tried was 14k front / 12k rear and it did make a noticeable difference.

I kept on adding more and more positive camber in the rear. The rear just build soooo much camber upon compression... it's nuts. I'd honestly try -1.5 rear and -3 front.

The brakes are awful. Dont use anything but the stock pads. Every once in awhile (even with stock pads) I'd flat spot all 4 tires. That's my biggest reason for not wanting to campaign the car anymore. I could never figure it out. Sometimes I'd just be trail-braking in and... wham... the front tires lock up and I just flat spotted the crap out of them. That was just so frustrating... and expensive.
I dont think this problem was very common with stock suspension... however, the stiffer the rates... the worse it seemed to be. This cars brakes killed my confidence.

You'll need a full tank of gas or else you'll fuel starve. As you know, the tank is huge.

I modified a set of kine / AmS camber arms and got -3.2 front. That's your best bet.

The car will make 300 whp with just high flow cats and a tune. That's plenty until you've figured out the suspension.

I'm selling a set of bride seat brackets and the modified front camber arms at the moment. just an fyi.

Best of luck! Hopefully they'll move the car to STU where it belongs!

You mean the brakes are excellent and the STR [strike]tires[/strike] class arent suitable for the weight of the car.

What happened to your ABS?
