STF Build

I'd run the 3 in HS in '09, didn't really care for the car and have been running ES in a '94 R-Package Miata since, but now with STF around, I'm gonna start doing some "casual" STF prep to the 3 here soon, for events I don't care to be hyper-competitive at, but would like to just hop in the car in the morning with a tire gauge and a cigarette-lighter air compressor, go drive, then drive home.

I'm gonna take care of some low-hanging fruit maintenance items first, trans fluid (Redline), and brakes. Recommendations on pads? The Miata needs a harsher compound in the rear to combat front brake bias, so run stockies up front and HP+ in the back. I'm thinking HPS all around for the 3, but I would occasionally run into ABS ice mode issues on the car in HS, so want to avoid that.

Next I'll look at picking some some Konig Feathers in 17x7.5 w/NASA Discount, 225/45/17 Star Specs. I would be using these to drive around on most of the time, so need TPMS as well, that's pretty much a plug-and-play, correct?

As for suspension, just thinking of throwing on a big rear bar (Corksport)? And then the Mazdaspeed coilovers. Recommendations on front camber plates for them? I've also been told to pick up the Mazdaspeed adjustable rear camber links, but can substitute if there's a much better product in the same price range. Would also probably do a Dynotronics reflash just for easy power / economy.

I'm slow.

Re: STF Build

I have no real info to contribute... but will follow along :P

As for the TPMS though, you just install them as normal, then turn the key in the on position, then key off for 15min, and next time you start it you are good to go.

So basically just but them in and drive like normal and you'll be good to go. The process is in your owner's manual... but like I said there is nothing to it.

Just make sure to buy a good OEM sensor or equivalent... Siemens makes the factory sensors.

Re: STF Build

Picked up some off of another Mazda3 a couple days ago, so that should be good to go.

Re: STF Build

tires first Hankook RS3's seem to be the best, Dunlop's second. then get a Coil over kit. I don't know what coil over is best, but I went with the KW V3. The rest is real good icing

Re: STF Build

Thanks,

I'm fully aware of the seat time issue. I've been autocrossing since '04ish . Still don't have nearly enough!

The RS3s I worry about on colder days + in the wet. You don't have that out west . The Dunlops seem to beat them out there. I really wish they'd open the class up to wider wheels (STX rules) to help the heavier cars compete, but that's neither here nor there. I'll get my letter in once I see Nationals results this year.

I know what'd be "best". A set of Koni 28s, Motion Control, AST Doubles, Penskes, etc. There's really not the budget for that for this car for me. So I'm sticking to the Mazdaspeed coils (KW V3 w/o the remote reservoir). Just trying to find camber plates that work with them. Emailed Corksport today to check in on that.

Congrats on the win in San Diego! How'd you end up PAXing? (Can't find results anywhere).

I'm slow.

Re: STF Build

Yup, I was thinking California weather, Sorry. I paxed 81st not great, but for the lack of mods I'm happy.
I've been autocrossing since April 1974 and I'm still learning!!

I wish Andy Hollis came out, even if he beat me I'd have a better idea of where I sat. He Paxed in the top 30 at the last Pro.

Don't get too uppity on the wheel size, I ran 225/60x15 with 15x7 rims on my 1982 ESP Camaro (1988) back in the day and that wasn't too undersized. The car was heaver than my 3. Oh and my 3 has 20 hp than the Camaro did stock! Yes time change, but it's not a life ender if you don't get the bigger wheels.

Re: STF Build

It's more to even up the class between cars like say, Hollis' 2 and the 3. He'll have 500lbs on us.

This is a casual build for me and won't even be my primary autocross car, but I'd really like to see this class do well.
