See OP. I started this thread :-) it's a really basic setup, but after shopping coilovers I realized anything I was really interested in was out of my budget this year.

Also, damn, you're detailed! I just sub'd your youtube channel. Can't wait to see more. I got lazy and stopped filming a couple of years ago. I love it when people make good ones though, i'll be watching!

A 20mm front swaybar and a 16mm rear is IMO a good set-up without too much of that "big bar" feeling. Might even try just the front.

Ive had my Tarmac springs for about 61k miles. For 99.9999993% daily driving and the rest auto x.

I'd for sure recommend a bigger front bar and leave the rear bar alone.

So many options to choose from:
Suspension Techniques (ST) 19mm
Everybody: 20mm (arguably the best)
Progress: 20.5mm
Blox/agency power: 21mm

I've been rocking a 22mm front for the same 3 years and while I thought the 22/14 setup was the bees kneez, I feel I've been missing out on rotation ability for a long time.

I'm a bit worried about further dialing out oversteer. I'm enjoying getting better at autoX and building the car to be better too, but i'm not yet to the place where i need it to be as competitive as possible, and I want the car to still feel playful. As my only car, it's a balance. Someday it won't be my DD and i'll make it more focused, but for now I like the tail a bit happy!

I like the car to be pretty neutral, but I want it to have a slight propensity to oversteer when pushed, rather than understeer. As such, I have it set up so that the rear gets a bit slideways when I really push it. I find light oversteer easier to correct without losing time, and without sacrificing the "racing line" too much. Understeer sucks because it causes me to miss apexes if I don't slow down a bunch.

Plus it's fun when you're going balls out, and you look more badass, when you're slightly drifting with some decent slip angle, as opposed to plowing wide with understeer. Makes for better photos, too. Lol.

There should be lots of ways to achieve that, sway bars were already mentioned but I found alignment can give one end of the car waay more grip than the other.

Do you have camber bolts+plates and rear LCA's yet? If not, camber up front can unlock a lot more grip when you get up and over -2.5 degrees imo, if you leave the rears at the factory -1.5 or so it should keep the car very playful.

I ran my car totally OE except for camber bolts+plates up front for a few months and when I got it just right it felt straight up magic. That's kind of why I'm a bit excited about this setup, seems like exactly like what I want, a little lower, a little stiffer, great damping, full alignment, and swaybars to tune past that and done.

100% agree. It's more fun, and while wheelspin technically is slower, when you're cooking a TAD but the car rotated it doesn't feel like you lost any time. Like a nice slightly squeaking <5 degree powerslide seems pretty darn quick. (and looks/feels amazing).

It's faster, anyway. In the slalom, for example, you want the rear-end of the car to move a bit like a pendulum. That allows you to "pivot" the car more tightly around cones.

Keep in mind that you can do a lot with tire pressures too to fine-tune the balance of the car at an autocross event. Even a 1-2 PSI change in the rear pressures can make a noticeable difference in how tail-happy the car is.

Good call.

I have had SPC front bolts for a few years, and recently dabbled in rear LCAs but went back to stock for this very reason. The lowering gave me a little neg camber in the rear but I wanted to keep it a bit more vertical so it didn't have TOO much grip.

Before the springs, the front was roughly -1.6/7 and now i'd say it's closer to -2 or maybe a bit more. SO it's definitely has more camber up front, and that's fine with me for now.

You guys don't find that setup to be too tail happy? I had a 20mm front and 16mm rear swaybar setup a while back and found it made the back a bit loose for my taste. Now I'm using a 22mm Strano bar up front and the stock bar in rear and it feels really well balanced. I'm on RCE T2's, so the even spring rates front and back may make the difference.

It can be a little tail happy...and just the front bar might be faster for auto-x (for some). But it sounds like CatDaddy and Stang07 like the car with a little more oversteer.

I forgot to mention the 22mm Strano bar is tubular, not solid. I'm sure you guys know that, but some people may not. Just wanted to avoid any confusion.

Absolutely. If I get to the point where i'm trying to compete at solo nationals, I may change my tune but for now I like a little slip and slide at the limit.
