Still having stability issues

redondoaveb · 07-18-2019, 04:49 PM

I was just looking at the alignment sheet on my old car and they had my rear toe at 0.15" and front toe at 0.10".

OptionZero · 07-18-2019, 06:10 PM

at minimum, SPL FUCA
used sets pop up all the time but since you're trying to fix the problem you can just get a new set of those now. SPL FUCA adjusts both camber and caster to a much larger range than the SPC crap

I would directly talk to your last tech to see why he left the caster off

It’s also time to take matters into your own hand a bit, need to educate yourself in what camber, caster, and toe do. Even if you have a miracle mechanic, you still gotta know your stuff, as that’s half the battle.

Ok kool, I will order the SPL FUCA.

Btw, is SPC front camber arm and the SPL FUCA replace the same part on the car?

Goddamm if I knew that I would have gone with SPL version in the first place, I had my SPC ordered from Z1 so I had to pay for international shipping anyway

Ahh man, I can't recall it but I think I remember choosing SPC because it still seemed to have good reviews by ppl on here.

Im pretty sure youve been told to go spl before

I know i say it in every post

shadow85 · 07-18-2019, 06:40 PM

And since it was mentioned my rear toe out needs attention, what part should I be looking at buying to fix that up or should that already be fixed with eibach rear camber/toe kit thats already on the car?

OptionZero · 07-18-2019, 07:16 PM

Yes

So I emailed SPL aswell with my alignment report to see what their suggestion also is.

This is what they replied with:

"I would get bumpsteer adjustable front tie rod ends and check the rear bushings for the dartiness. A camber arm would not be a bad idea in the rear to get the camber equal on each side and get rid of the deflection in that bushing. The traction arm might also help if you are lowered to keep the toe from changing in the rear to get the car from moving around on you."

You need the SPL upper arms to adjust for camber and caster. The dartiness is from the rear toe. Once you get the SPL upper arms. Try these align specs.

Front camber -1.7
Caster +6
Toe 1/16" in

Rear camber -1.7
Toe 1/16" in

These are good street specs. If you want more of track spec. You increase camber, and start to get the toe closer to zero. Then the car becomes darty.

OptionZero · 07-18-2019, 09:04 PM

i would PM BGTV8 and get a recommendation for a better alignment shop

Talk to them, make sure they understand the problem and can handle it

Rusty · 07-18-2019, 09:13 PM

Your caster numbers show a right pull. Which ever side is closer to zero. That is the side that it will pull to.

Your absolutely correct. It pulls mostly to the rite and very much more pronounced when trying to launch it. At which point the aggressive TC kicks in cuts throttle.

OK I will note this down and present it to the next alignment centre. Curious about drag racing aswell mostly, would these settings also be good for drag racing or would I need a new alignment altogether for that?

At some point in the future when all my car issues have been sorted I would love to hit the strip.

Rusty · 07-18-2019, 11:19 PM

For the strip. The rear camber should be close to zero.
