hey guys i have a question. Just got wisefab front kit but have no clue how to adjust ackerman. I have the ackerman spacers but cant figure out where they go and how to put them and how to set them up

LuckyX2

Thanks for the answer. I see you suggest they work best with the S14 subframe. In my situation (SCCA Street Modified) I can't use conversion bushings for the S14 subframe on my S13. So between a S14 subframe with rubber bushings and a S13 subframe with solid bushings, what would be the best compromise?

Drifters i know in the french championship remove the roll bars at the front because it rubs on the wheels.

Also, considering they do not corner weight the cars (and they crash more often than regular race cars), using roll bars cause the suspension to preload and make the car unpredictable. So they don't use them. They counter roll with springs.

What does the rule say specifically?

The rule explicitly prohibits offsets bushings to mount a subframe.

Has anyone actually measured these Megan Racing ball joints?
I see them everywhere and was just wondering if they just spaced the ball joint up.
I know for the price and quality its better to go with something like Moonface.
just wondering if anyone has actual proof. maybe a side by side picture

recommendations on a tie rod setup on an s13 with a 15mm extended lower control arm?

I had teins on my last car and I loved the spacer, but I'm not sure if they will work with the FLCA extension.

thanks!

Def

Can SM relocate suspension mounting points? If you can, just drop the front RLCA mounting point down around 3/4-1" and it's about the same geometry.

It's faster than an S13 subframe, with much better traction on corner exit.

No, you can't.

If you only have 15mm extension on both sides, I would just suggest tein inners/outers or moog outers, and then pick yourself up a rack spacer.

I would probably do the S14 subframe then with stiffer rubber bushings.


I wonder if you can get things to seat up with energy suspension urethane bushings. Might be enough compliance, might not.

Highly doubt it. You'll push the center pins out and never get them back in when you're trying to put the subframe back in the car.

Def

You could drill the ES bushing to give it compliance in that direction. Then hopefully things are mostly locked up once it's on there.

And I don't mean make an offset bushing, I mean drill a compliance hole on the side of the bushing that is compressed, so that it can more easily get distorted into that shape.

Yeah I see what you're saying. A liberal reading of the rules

LuckyX2

There's also Jason Merritt's solution. Maybe that plus an ES "compliance" bushing would be best.

Thanks man! s13 or s14 outers?

EDIT: Just read on tein's site that only S14 outers will thread into the tein inners

derass

What's going on with this? How are the bushings modified?

e1_griego

They aren't modified, just using the deflection in the rubber to mount s14 subframe to s13 chassis.

LuckyX2

Well he has that added metal piece making the mount "solid", no?

Not at all.

There is a metal retaining cup stock that does exactly the same thing. That's just a flat piece of metal instead.

LuckyX2

Hmmm, guess I'm just forgetting how the stock bushings are, I went solid a while ago.

He refers to them as solid though:

he got 2nd at Nats last year and his car is built to the rules.

Lemme txt him and see if he'll reply here. Or you could send him a PM or something.

kapower

I effectively solid mounted my subrame pictured above by modifying the mounting hardware and not the bushings. I believe that some people deflect the inner metal spacer then weld it to the subrame off center.

. I'm OK with any sort of modification, but straight solid aluminum bushings are specifically not allowed. I think the intent of the rule is to prohibit relocating your subrame, and i think it should be re-worded. In the spirit of street modified I believe all popular modifications performed on popular street cars should be allowed. The intent of street mod is as a recruitment class for the younger generation that drive popular modified cars that don't fit into other street classes.

u guys seen the new lock kit gktech has in the works

one piece lca/tension rod , their new knuckle, and offset tophat

love you guys keep this thread rollin

LuckyX2

Yeah, I never said that I thought the bushings themselves were solid, just that he "solid" mounted it. I wasn't trying to accuse him of breaking the rules. By "them" I meant his mountings, not the bushings, sorry for the confusion.

Thanks for the reply. So how is your setup more effective than the metal cup that greigo mentioned? And yes, I agree, pretty silly that we can't use a simple bushing to allow us to install a semi-common modification.

Love your build btw and hope to see you at nationals someday when my car is done and I'm (hopefully) a better driver. I'm aiming for next year currently.

anyone having good results with the gktech rear knuckles? Bummed out not getting to drive tomorrow. Had my rear suspension apart for 4 weeks now in anticipation for mines

ka-titties

i've heard great things about them so far.

Apex Eight

Can anyone with personal experience regarding an S14 to S13 rear subframe swap comment on its improvements?

Croustibat

I know, this does not answer your question at all, but you need to think about this before doing anything.

There are LOADS of mods to do that will give a better handling before that, and if you plan on competing, some classes don't allow this mod.

Basically the s14 subframe has less antisquat, but antisquat is dynamic and you already remove some by lowering the car. I think the TDP rear suspension kit actually adds antisquat...

Unless you already have quality suspensions, ball joints everywhere, front knuckle kit, sticky tyres and on and on (or are planning to), this really would be a waste of time.
