So last week I was able to buy a used Mazdaspeed accessory CAI off of the forum. Came with 2 filters and 2 brand new bottles of cleaner. Install went very smooth except that the original owner forgot to provide the rubber vibration mount. Quick look in the garage and I managed to find a spacer that fit perfectly. Butt dyno likes it, seems to be a bit more power around 3k RPM but haven't had a chance to get some runs with it on course. Since this is my first car it's been a learning experience as far as mods and what to focus on first and what to leave till the last part of a build. A few things I jumped in to quickly on was the rear swaybar and the KW V3 coilovers. The lack of camber plates really hurts the front suspension and I probably should have bought the BC racing Double adjustable or just stuck with their single adjustable. That being said I'm very happy with how the car handles now and I can't imagine going back to a stock handling Mazda 3.

I ordered a Hotchkis rear sway bar, but they were on back order and won't be here for another week. I'm not sure I'll be able to test that change before the DC tour which it looks like I will be attending. This 12 hour drive might be a little brutal and I'm not looking forward to sleeping in the car but sometimes you have to make sacrifices for things you love!

yeah, front camber is a must in a fwd.
Fairly certain even a blow suspension or racelands with -3.5 degrees camber up front would be faster than a very good setup that has no camber.

Gotta keep the tire flat through the turns! That matters more than anything else at the end of it.

Used corksport camber plates for 200 sound good? That's the only way I'll be able to get more camber other than slotting the strut tower more but the metal is getting harder and harder as I slot them.

So my Hotchkis rear swaybar came in after being back ordered for about a month. Installed it and the split collars that go on the inside of the chassis mounts and the wrong size. Sent me 1 3/8 instead of 1 1/4. They told me they wouldn't be able to overnight me the parts and won't guarantee that they will be here before I leave next Thursday.
Overall I'm very disappointed with their service, was back ordered for 3 weeks and then once they had the parts back from paint they weren't going to ship them for another week. Probably the last time I will order from them.

New collars came in the mail thanks to Amazon! Got those on and the swaybar install is finally complete!
Took the car in to get the alignment checked at a newer shop, turns out none of them know the correct procedure as to how to properly check a vehicles alignment. The Hunter machines are top notch and I have been trained on how to use them properly and showed the shop what they did wrong. Needless to say after spending 2 hours I came to the conclusion that my numbers they gave me were way off. Came home and used some simple trigonometry to calculate my camber here are the results:
RF: -2.7
LF: -3.1
RR: -1.6
LR: -2.0
Need to slot the right front a little more to get it closer to -3 and I will be happy. Also going to change the rear camber to get it closer to -2 if I can.
Front was toed in 1/8 which will be fixed, and the rear was perfect on the toe. Since I don't trust the numbers the shop gave me I'm not going to even worry about caster for now.
That being said all of that will be changed before the DC tour which I leave for in 3 days! To much work still needs to be done!

Well got back from the DC your after driving strait through for over 13 hours! Before I left when adjusting my camber I broke one of the bolts holding the strut to the tower, so that was fun.
The DC tour was awesome and it was cool to see how I stacked up against the other real STF drivers. Shout out to Daniel and his co driver for kicking my ass! Really I think I'm almost there as far as setup and driving. I was basically 1-1.5 seconds behind them on raw time on both days. I account most of that to having 17's instead of 15's as well as me still trying to learn the car. I'm going to keep driving hard and hope to really dial in the car before the end of the year.
All new bushings front and rear are on my to do list and I think that will improve the car by a lot, the 15's should be here within the month so I'm looking forward to how the car will end the year.
Locally I will win my class, and I'm hoping to step it up and win my state championship as well.

Quick question as far as rear camber the corksport camber arms are legal correct? I think they will be way easier to adjust and look like a better unit than my SPC's.

That's a negative. The Corksport rear camber arms use a spherical bearing, which is specifically prohibited in street touring. Furthermore, metal to non metal ratio must not increase in any of the bushing points.

I didn't think they were legal just making sure! Also is the RSX type S supposed to be in STF? As of the June fast track it's not on the STF list? Since there is a base model don't they have to differentiate between which models are allowed?

Anytime Ken, better to ask questions before you buy and install part than after. It seemed you assumed the other way though.

I'd be sure to thoroughly study the Street and Street Touring rules, especially since you're competing on the national tour now. If it doesn't say in there you can do something in those rules below, you typically can't as a rule of thumb. If you have questions (which you should) keep asking, but try to find it in the rules first. If you're committed enough to drive 13 hours to an event each way, that tells me you should be committed enough to thoroughly study the rules too.

You seem to be a natural at autocross based on the results I've seen vs the very limited amount of seat time experience you have. If you continue to improve, and start directly competing against the top STF guys for trophy and/or contingency spots, they will look over your car more carefully than they do right now, and you want to try to ensure everything is on the up and up if that happens.

As far as the RSX is concerned, that page has always just said RSX. I think they did clarify in a past fastrack that it also includes the RSX Type S, but I'm with you, I think they should put it on the page.
