Or to look at another example, the nb, nc, and nd miatas are all split on purpose so you aren’t allowed to do cross generation engine swaps. |

That is a factor of full prep (csp) vs limited prep (dsp) as update backdate is not allowed in Limited Prep. |

The information in all the prior STX threads was great, and really helped a new guy figure it out, so here's my contribution.
This season will be my 3rd. Been slowly upgrading and growing with the car. 2019 BRZ Base - Tein Mono Racing coilovers, 10k/10k springs - Perrin 19 mm front sway bar set full stiff. - Stock rear bar - SPC rear arms with DIFtech bushings. I hate these. Squeaky and loud once i swapped the Difftech bushings in. The SPC LCAs should be grandfathered in. - 17x9 APEX ARC-8 +42 offset. Getting some minor rubbing on the front drivers side inner plastic liner. - 245/40/17 Falken 660s or RE71s New parts installed over the winter break are below. Looking forward to the extra power. I'm not sure how much of a difference it will make in times, but it sure feels a lot nicer driving around without the torque dip. - JDL 4-2-1 EL header - JDL OP and Quiet catted front pipe. - Stock catback. New local site has an 85 db limit. Stock catback doesnt sound half bad with the catless 421. - CSG Ecutek tune - STi motor mounts - Torque Solution Trans insert. I also plan to go from 3.5 to 4 camber in the front and try some A052s once the falkens wear out. Last edited by gordo52; 02-03-2022 at 12:10 AM. |

Real happy with whiteline rear lca, same as spc but with a poly bushing inboard, no noticeable nvh impacts vs what was there before.
Got em on tire rack, great shipping once they arrived stateside. |

Why does everyone go for rear lower control arms instead of rear upper control arms?
I would think getting camber from pulling the top of the wheel inward rather than pushing the bottom of the wheel outward would be more ideal for suspension geometry and put less stress on the components. You would also get more similar fitment to the front where you are primarily getting camber from the top with camber plates. Mismatches in wheel fitment also seem to negatively effect the traction control systems in these cars. |

Upper and lower control arms are not separated as much as the full diameter of the tire. So pushing the bottom out, will bring in the top of the tire. Not as much as adjusting the upper control arm, but adjusting the lower, will bring in the top of the tire some.

Recommended spark plugs for STX tuned cars?

Adjustable bushings in the upper arm should be legal though and cheaper then both, but more of a pain. This isn't a Miata so the rear suspension isn't designed to be adjusted up there. You're probably right in that it's *theoretically* better, but not enough to show up on course when missing an apex by a foot will add a tenth to your best time. Especially given that you're paying an extra $500, that's almost 2 yokes! Edit: +1 on stock plugs, high compression engine with weird Toyota direct injection system, not sure if the aftermarket is going to spec anything 'better', there are cheaper options but I don't think there's any gain there. |

That’s the strut section, for the rear of an 86 h.1 is the correct section:
On double/unequal arm (e.g., wishbone, multi-link) suspensions, only the upper arms OR lower arms may be modified or replaced, but not both. Non-integral longitudinal arms that primarily control fore/aft wheel movement (e.g., trailing arm(s) or link(s) of a multi- link suspension) may not be replaced, changed, or modified. That’s from ‘21 rule book, I’m hoping the updated wording goes into the ‘22. |

Yes, but the bushings are free as long as they aren't metal. The control arm remains stock.
