STX Rules and Setup Questions

How about these??? Legal or not




Again...just Stimulating Thought

Are RLCA'S allowed? i cant find anyhing about them. I would really like rear camber adjustability. For the strut bar i think you can only use a 2 point. the car doesnt come with a factory strut and the rule states a 2 point may be added. For a 3 point it doesnt say you can add one.

No. . There is no provision to replace the toe link and the trailing arm is explicitly not allowed. I'm assuming you mean the blue pieces, of course the camber/control arm is replaceable as long as the right bushings are used, no spherical bearings.

@dwx ... ...thanks, you must be the Rules Nazi in your region...... this is good, that way people become familiar with whats legal. Half the reason alot of folks don't go Autocrossing is that they are afraid of what they have done(mods) is wrong, Whereas you and I build the car according to the Rules..because we have a plan..

thanks for the assist ... If we can get others to look at the rules first... instead of just throwing parts on it we will have a better educated community.

All i meant was for the rear lower control arm. not the blue pieces but that still very useful to know. the car stock has no rear camber adjustability and i would really like some. Thank you.

if I do lca's and go turbo what class are we?

Iknow that the seat with rails must weigh 25lbs but what about harnesses.4 or 5 point. Thanks, I really appreciate having rule nazis who prevent me from unknowingly messing up.

If you or any of the FRS/BRZ contingent run the strut brace at a national event and even some big local events, I'm quite confident it will be protested. The Hotchkis site even calls it a 4-point. I already gave my opinion on it here.

You technically have two options for rear camber adjustment, both are by Whiteline. One option is the rear camber adjustment bushings, which replace the rear upper control arm bushings. They should be legal as the bushings themselves look to be a direct replacement, and the metal insert doesn't contain any additional metal, it just has an offset hole.

The other option (which I don't think exists yet, but they were at SEMA) are the Whiteline rear lower control arms. These are the only RLCAs that are STX legal since they still have a poly bushing where they attach to the subframe - all the other ones I've seen (Cusco, Agency Power, DME, etc.) use a spherical bushing, and would therefore be illegal.

+1, these are absolutely not legal for the class. Not that it's much of a concern, as they are a complete waste of money to begin with...

The SPC one also appeared legal.

They are also probably half the cost of the Whiteline at 290. And come with an offset bushing for the toe link if you need it to account for the camber change.

Street Modified. A class I think the frs and BRZ could be very successful in if prepped well enough, but it takes $$$.

Powerflex also has rear camber adjustable bushings as well... I have them up on my website. There are so many I gave them their own menu on the left of my webpage (Powerflex not those bushings specifically). Also I want to note that ALL the Powerflex bushings listed have the correct photo's attached... those are not examples, those are the actual parts.

Sweet. I already have those but have neglected putting them on due to not having complete understanding of the rules. Also the 290 is for each one.
