STX setup sharing thread (2021)
Well, the last one was pretty well received, so here's the 2021 thread starter.
No, really, *this* year I'll put the coilovers on the car! I have collected some small bits (sway bars, engine/trans mounts, etc), so really, this time I mean it Opinions on the KW V3 coilovers? --Bryan

I'll put my setup on here.
I threw the car together last March, then only got to run a couple of events all year. 2016 Scion FRS - ProParts Megan Racing coilovers - using Megan camber plates and front end links - 400/400 springs - Eibach 25.4mm hollow front sway bar (leftover from SSC set up), set on soft - Mann rear bar - Racer X rear end links - SPC rear arms with DIFtech bushings - JDL 4-2-1 EL header - JDL OP/FP combo - Invidia Q300 catback - Perrin inlet tube - Xero Limit Ecutek tune - Whiteline transmission insert - Whiteline subframe bushings - 17x9 RPF1's +35 offset - 245/40/17 A052's Car was too low and I need to shift the front subframe to get the camber numbers I want up front. Never got around to it with Covid and then Nats getting cancelled. I've got an Anti-Gravity ATX20 Restart and Mele Battery Box waiting to go in the car and I may do a few other things. Hope to run a "normal" schedule for myself and my co-driver, which would be about 8-10 national events, and whatever locals I can hit at Bristol/ZMax/Huntsville, but kind of in limbo with Covid and possible travel restrictions related to my job and I'm having a lot of fun throwing frisbees. Hopefully, STX numbers make it worth traveling. |

Copy and paste from 2020 with a couple updated items. I won't be running STX for 2021, I'm codriving within SSR. Anyways my car has a flex fuel kit going on it for E85 and track use. I think my days in STX are done.

I'm running STX again and probably for the next year or two, realistically. Don't want to switch to a 'big tire' car and the ownership costs for this car seem pretty low now that I've spent the money on parts. (I also have an s13 track day car, a miata with vvt/xidas/etc, and a fiesta ST daily driver, so the brz is the simple one).
Suspension: MCS 2W remotes 5k/9k (275/500) rates Raceseng CasCam front plates, 1" top hats in rear Karcepts Front bar Mann rear bar Alignment is generally -4.2ish*/-2.1*ish camber, 0 / -1/16" toe. Racerx LCA with a delrin bushing (instead of poly) Racerx Rear endlinks Engine: Cosworth or k&n drop-in filter Ace A350 header JDL Ultra quiet front pipe CSG touring86 exhaust Perrin oil cooler Other: OS Giken lsd in 1way config Whiteline subframe, diff and trans inserts STi motor mounts I run a few different sets of konigs 17x9 +40 with 245/40s. I mix between rivals and a052s. Still run a heavier miata battery because I had one laying around when the 35lb beast died. Maybe I'll buy something fancy this year. Stock brakes with Stoptech pads f/r. |

What kind of caster are you guys running for AutoX? I’m looking at finally getting some camber plates for my Tarmac 2’s. Been running them with stock top hats for years and am maxed out at -2.7 with the crash bolts. Not sure if I really need any additional caster adjustment or not though. I’ve heard too much can cause issues with the power steering?

I want to say mine is basically at stock caster -- is that 6*? I can't really remember.

I prefer less caster.
With a lot of caster I feel like I'm picking up the inside front of the car with the steering wheel. When I drove the 914-6 in my avatar I could barely finish the run the steering was so hard. I told the owner it felt like a lot of caster. We popped the hood and saw the caster was maxed. |

What is the purpose of the Mann rear bar? Ive read its softer than stock? Does it have to do with the Torsen diff, or is it just to keep the rear planted on heavy turn in for autocross? Would it be beneficial in a "touge" setup? (tight hilly backroads)

- There are 3 settings, the stiffest setting is supposed to be equal to stock. - I don't see any reason to run a larger rear bar on the car, regardless of diff. Yes, it allows the rear suspension to articulate. - Over a stock bar? Not really. Over a bigger rear bar? I think so. I drive my car on the Tail of the Dragon maybe every month or two. Rear bar is just a part of the equation, but the car is much more predictable with a lot less computer intrusion with the current setup compared to the SSC set up with the Eibach rear bar. |

I have Raceseng Plates with the +1 of caster. So I have it set to that with whatever that ends up being. I have never measured it, I don't really care not knowing what it is. I think it's worth it to try and gain as much dynamic camber as you can. I personally have not dealt with power steering issues aside from hitting NCM Faux Rouge at 114 MPH and loading up the car (at at sinkhole)

I’m pretty much the same setup as last year. And if I remember right I’m right about stock caster settings. I tried running a ton of caster and didn’t like how the car felt in slower transitions.
Power mods: Grimspeed intake, Tomei UEL header and overpipe, highflow cat/ front pipe,Kartboy crank pulley, OFT tune. Suspension: RCE T2 400lb front 500lb rear springs. Whiteline 20mm front bar on stiff setting Mann rear bar(settings depends on surface) -4.2 front camber with 1/16th” toe out -2.5 rear camber with 1/16th” toe in AP Racing Sprint front kit with Ferrodo DS2500 pads front and rear. OS Giken LSD with the Lugod specs Rear subframe and diff insert bushings. Light weight battery. 17x9+35 RPF1 with 245/40R17 Yokohama A052 or Falken RT660 for local events. |
