SPL Traction Arms, any experience or knowledge

[SPOHN]

Basically as the the title states. Looking to buy and want to get the best suspension handling out of my car. So has anyone had experience or know how to get the most out of these?

I have a set but haven't installed yet. I do have other SPL pieces installed. Very nice stuff. Allows for easy alignment. I personally believe other two arms are more critical. Especially for us guys running true coil overs in the rear. Nice clean way to delete that ugly stock arm with spring holder.

Benefits of adjustable traction bar? I'm still figuring that out. Trying to think what it will do? Guess it would impact toe and maybe caster? Not sure. I went more for the solid bushings and high quality design. Won't know how it impacts alignment until I have it on the car and start dinking

You should be able to limit the toe change during travel by measuring toe at different levels of travel and adjusting the length of the traction arm so that you can keep the change as small as possible. I don't think it's possible to eliminate toe change completely, but you could get it pretty close. Since your car is lower the stock length may or may not be ideal... this will give you the ability to fine tune it.

Since they have rod ends I'd also look at getting some good rod-end seals (not sure what they come with) or some rod-end boots to keep them greased nicely and as quiet as possible.

But like Grant mentioned the solid bushings are going to make the biggest difference over stock.

After spending 10 minutes on the phone with SPL the other day the best answer given was your deleting the mushy bushing that induces some bumpsteer to a solid machined bushing that helps reduce this action. Which I'm thinking of ordering there hole bushing replacement kit. Costly but I feel it's worth it.

Yes it is. The performance diiference in my Porsche Boxster from stock bushings to monoballs was astounding. Anything that holds alignment better and frees up suspension rotation at pivot points is good.

I just wish SPL would do a front arm! please please pretty please!

Eventually all bushings On my car will be replaced with spl parts. It's about half the cost of my Boxster monoball conversion too!

I did talk to the guy at SPL on the phone the other day for about 10 minutes. He said they have sponsored two Z's that are racing in the continental tire sports car challenge this past weekend that are running there front camber arms and will be waiting on there report to make the decision if those will be the ones they put into production in the next month. Which I did reply you've said that before and that day hasn't come. But we'll see. I told him there is a market for them on the boards.

Got mine from THMotorsports too! Best deal I could find as well.

Just to be 100% completely clear...Doran Racing DOES NOT run SPL front control arms.
When we first got the car we had a conversation with them and received their parts... after seeing them and talkin with Grand Am we decided to go another direction and make our own parts.
At Barber Motorsports park we ran Hotchkis front and rear sway bars....
After running he car for the first time.... we designed our own sway bars as well.
The Hotchkis sways are a great product ... we were in need of a much higher range with adjustability.....
Again.... We do not run SPL front control arms.

Yea must be. But who ever comes out with good front control arms first is getting my money that day. I'm reworking my hole suspension.

Galeforce,
Great meeting you and your family this past weekend! I hate that your son didnt like sitting in the car. That would have been an awesome pic.

You are correct, SFR Enterprises is sponsored by SPL Parts Pro (Sean Farrah).

Also to be clear, we are a SPL Dealer as well. I do not think we have the SPL 370Z components listed on our site YET...I will need to double check. Otherwise we can also obtain any of their parts as well.
