Who's making the move to STU?

It was too pushy, I had the Eibach bar already.

FYI the z1 FUCA's are technically illegal in STU.

I ran my first event in STU trim this weekend with 285sq'd (18x10.5)
It was 35 degrees.. it's a shame being sideways eats up so much clock

Confused about this too. Only possible illegal aspect I could see is if the metal to non-metal content is off versus the factory FUCA. If someone protests you for that with these particular arms they deserve to be ridiculed by everyone around.

z1 2 Piece Rotors
Penske 7500DA
1000lbs front/896lbs rear springs. Change as necessary
OS Giken
Race seat of some sort. New SCCA rule Race Seat + mounting equipment must weigh 35lbs.

Spoke with a couple of veteran and they recommend tires, suspension and differential as the 3 must haves.

Dumb question, but where would you get your 1000lb/896lb springs from? I don't think there is such an off-the-shelf offering.

Justint5387 · 04-11-2018, 04:33 PM

896lb/in is 16kg/mm. Swift offers that.

Eibach and Hypercoil has 1000lbs

Is that what you were asking?

It'd take a true asshat to protest over something like that -- but it's something to be aware of.

lets talk coilovers for a minute. I want to go with something in the $1500-2500 range. I want the dampers to be able to be serviced in the states. I know I can get this from Fortune with their 510 series. I also know that the mcs single adjustable are around this range. Looking for thought and feed back on other options to consider.

I trust the guys who actually use their cars over the opinions in the general suspension section.

nismosis · 04-27-2018, 08:46 AM

What systems are out there which do not change the rear to true coilover? I'm aware of KWv3, but are there others?

You don't have to get the springs from the people you get your dampers from. So long as the dampers are valved correctly for the spring rate you will be using that's what matters.

I have AST dampers and when ordered I just told them to supply springs to the specs I gave them (diameter, free length, and rate). I'll probably be picking up more springs in the near future to test some alternate spring rates.

Many of the good ones do not. AST, KW, Ohlins, MCS, MCA, Fortune, Penseke. Also like Gomer mentioned, if a company makes a good damper but it's a true type, you can always order up a set of rear perches to mount in the stock location.

You can talk to ProParts for some 28 or 30 series Konis

I disagree. I contacted the SCCA before I bought the z1 FUCA Street kit to run STR (last year). They looked it over and gave me the green light. I have the full email conversation.

Without doing a deep dive into the 370z's specific metal to non-metal ratio for stock bushings, all they were most likely commenting on was the fact that it "appeared" compliant. The guys at the SCCA main office aren't experts on every vehicle ever made.

As was previously pointed out, you most likely have nothing to worry about unless you come up against a someone willing to suffer the ridicule a weenie protest like this brings upon the protester.
