Can we talk about sway bars?
So, I get the general idea about beefier sway bars to hold the body roll. In general I love the gokart like feel of a car with very little body roll. I still remember the thrill of a buddy's old '74 Porsche 914. It wasn't a fast car, but it was totally flat in the curves. My 86 reminds me of that feel a lot, but I'm wondering if I could accentuate that fun go kart feel further. So what happens if you take one of the twins stock and just swap with stiffer sway bars? My guess is that it will become more unforgiving about weight transfers that aren't perfectly smooth. Would stickier tires be a requirement? I'm ok with stock travel and dampening for "streetability", but a little more of that gokart cornering feel would be fun too, even if it doesn't make me faster on a lap around a track. Are you better of with stiffer springs all around to resist the roll, or can you do that with sway bars and still get the benefit of stock travel and dampening for comfort. Or, will this just make things overly twitchy? |

Imho just go buy some bars and try it, nobody here will be able to accurately describe what effect they will have for you and correlate it to your own expectations and desires.
It's a couple hundred bucks and they can usually be resold without a ton of hassle, hell try to pick up someone else's, there's a fair few 86s in Texas. |

I thought I would update for folks that might be reading through this thread. I went with the Blox Racing 21mm front 17mm rear sway bars on an otherwise stock, low mileage suspension. Blox had the set on sale for $250, so I figured it was a fairly low risk chance to give it a try. Not a huge difference, but I notice it most in the rear. Things aren't quite as floaty in back in sharp turns. Still comfy for street driving hitting bumps and dips and such, which is what I was after. Feels more level in turns, but hard to tell what is placebo because I expect it.
Not sure how I feel about the Blox quality, I had to drill out the holes in the front bar because the end links wouldn't go through. They were almost 1mm too small. My guess is they were spot on before the powder coating. It all worked out. I mean, its just a steel bar bent the right way with holes in it... |

I imagine it makes for a gentler landing when you lean into the bump stops.

Thanks Andy for the details - I have a stock BRZ with 17x7.5 wheels and michelin primacy 215 and Brembos + Sachs Dampers (all stock). If I wanted more grip are you saying I should basically just get better grip tires (hankook rs4?) and add some camber? (how much camber?). I've only been to the track 3 times - 3 weekends in a row actually |

If you still have OE alignment, more camber (especially front) will help a LOT to add grip on track and reduce understeer. Am i wrong that by now your tire outsides are rather worn? Starting numbers i'd aim for track would be -3 front camber and zero toe, -2.5 rear and slight rear toe-in of +0.1dg per wheel. Might not be the optimal, as it is also tires & track specific, and one should use pyrometer to find most optimal alignment, but will get you in ballpark.

I would definitely recommend a good alignment along with them. You'll need at least camber bolts, but with stickier tires you could also think about camber plates to get the camber you really need. For the rear, lower control arms will get everything perfect but aren't 100% necessary. Nice to have though. Toe arms a little less necessary than that, but also nice to have. To be clear though, all that is to just get things right and get a nice basic set up that performs well and keeps your tires happy. You're already out there having fun and that's awesome. Don't forget brake pads and you should start thinking about an oil cooler if you haven't already. Those are the important reliability and safety things. Oh and one great way to get faster is some driver's instruction! - Andrew |

I uhh...had some free time.

Im looking for track alignment suggestions.
My usage is mainly track, but the car is driven to the track (4+ hrs) and occasionally around town. (Not my DD) My car is a 17 PP with stock suspension except for camber plates and rear lower control arms. Tires are Hankook RS4 Ive got over 150 track days under my belt, including a few seasons of Spec Miata racing where I won quite a few races, but its been a long time since I drove anything other than a trailered miata racecar so I'm looking for a good starting point for this strut car on street tires! I like a looser car that rotates well. Its tempting to go straight for -3 degrees up front and -2.4 in the back but Im just not sure how that would wear tires on those long drives to the track. For toe Im thinking 0 front, and just a hair of toe-in in the rear, like 1/16 thoughts? |

If you like rotation ditch the RS4's and go to something like the Dunlop Z3.
