Spring rate help?

we could just do custom front sway bar but it wont be cheap....

I have had bars made cheap in past. Blade swaybars are pretty easy to make. There are swaybar guys who make custom bars as well.

If somebody put together a front swaybar kit that used Speedway's modular components, I'd be in for one. The arms don't have to be rotating blades, the regular bent steel or aluminum arms with a couple holes drilled would be fine. Blade arms could be a +$$ upgrade for the ballers.

I know Shamu, I've built a bunch for a bunch of different cars - but happy to have someone else do the work for once

Specifically for the Z, arms with the right bends, and mounts that space the center out of the way of the oil pan.

Zoren 370

Who should I be talking too i need to get 2 front 255/35 19's soon?

Shamu

Oil pans are over rated.

I suspect the market for a swaybar that only fits dry sumped 370z will be rather limited

lets get your damper settings dialed in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If someone needed that I would talk to Martin82 :P

Since my springs have settled in, today I noticed the car dropped a lot in the front. I was to lazy to remove the 2 way reservoir, sway bar, rear lower coil bolts etc etc then have a hell of a time spinning the lower with the 2 ways SS line hitting everything. So I just raised the car with the upper perch/lower spring perch. This of coarse adding a ton more preload to the spring vs just having the spring snug in the upper perch and mount. Negative effects? Car looks and feels WAY different. I had a racked rear end thing going on and could see over the hood. Now the cars sitting even and it looks like I'm driving a semi again.

Moving this over here to this thread instead of my journal:

I don't really know? I mean, the car certainly didn't get any worse for it. Both weekends on both swaybars I had fun and the car drove well. It was just seeing all the traction left on the table from the photos of the tires in the corner that bugs me. If I can flatten out those tires a bit more I can pick up more traction.

Ultimately I think I still need springrate to control the car's roll to really address this, but I think stepping down the rear bar was probably helpful and will continue to be helpful with the stiffer springs in play. The flipside is that for the moment reducing the rear bar perhaps reduced some of its unwanted effects on the rear suspension, but at the cost of allowing a little more total roll by reducing total rear springrate.

In any case, these are the best equivalent pics for comparison I could find from the photographer who was out there this weekend while I had the stock rear sway on. In most of these pics the situation looks improved, although in one of them it looks about the same as before:













I've got new springs sitting in the garage now ready for install, 900 front and 700 rear, so we'll see next event how that shakes up the situation.

Oh and youtube link to my upload from the weekend https://www.youtube.com/watch?v=U6BJpqH1js8

I was watching on youtube. Some ALM cars in slo-mo. What I seen was that most of them have really stiff suspenion set-ups with little suspenion travel. To the point of lifting the front inner tire. The outside tire is really loaded up. In your pictures. You've got more body roll.
