That is just wind resistance.

Talking to the Honda guys they were just shifting into 5th so they were doing 104-110 give or take.

Without another car on track it's impossible to have any data to prove our case. Good job building a car that ran the entire school and was able to compete, but I know you didn't feel competitive. Were the 2 Honda's schoolies or licensed drivers getting track time?

I don't know how the bspec board works, and I'm not positive without Toyota's support we'll be able to proceed forward.

I was really happy with the track performance of the old 2012 STF suspension and it fits the bill pretty well for B-Spec, but I don't think you could create a "kit" out of it because of the fact parts need to be modified to work.

If you want details I can post shock dyno data, but essentially it was the H&R Coilover kit with 7"x2.5"x350# front springs and 8"x3"x400 rear springs. The rear shocks will need to be shortened by 1" as they have too much travel and allow the spring to unseat, but zip ties seem to hold the spring in well enough. Car was reasonable comfortable on the street, I drove from Irvine, California to Lincoln, Nebraska with that setup, and didn't roll like a boat on the track, it was reasonable able to grip the inside front with minimal inside front spin.

Looking good! I'll post up pictures of mine today.

I'll be putting it on the scales and adding weight this week.

Updates ASAP!

[FHT_Racing]

I need better brake pads! The HAWK HPS crapped out.

[xnamerxx]

Make sure you get lots of weight, if your car is anything like mine you'll need to add 100+ lbs.

I had to add a bunch of weight to the front footwell and rear passenger seat area to get the numbers this close. Still running too much fuel though.

[xnamerxx]

Nice looking car :)

Yeah get rid of that street crap, it'll save you headache in the future. I'm running Carbotech XP8 I think, they work really well for the price, but I would probably get a set of cut DCT-60s

The black stripe looks good.

About the only "off the shelf" pad is a carbotech - typically they don't stock them, but can make them in a few days. We ran those for a year or so, but never really liked them. They have to much initial bite for my taste, and with no ABS allowed in Prod they tended to cause flat spotted tires. We had Porterfield cut a set of Hawk DTC-60 pads down to fit the Yaris caliper, and have never been happier. Very progressive pads, and with more than a year of racing on them they still look like new. Well worth the money.

I resemble that remark

How many tires do you have to kill before you hook the ABS back up?

[xnamerxx]

Probably never just knowing that a mistake will cost me $170 helps keep me in check.

[FHT_Racing]

Yep, with full gear, a little over half tank, and 40lbs on the passenger side it came out to be 2,375lbs :/

So I'm looking at a full tank and 100lbs.

I may try the Carbotech pads just to see how I like them.

Thanks!

Just need to get the cars out there and start recording some finishes, then spend six months trying to convince the CRB to take weight off the car.

[xnamerxx]

Well I'll be at the Majors event in a couple of weeks, just have to beg them to add a CRB data box to the car.

Just a heads up add more weight and run less gas. I was weighed at my last race and just barely made weight even though I put several more gallons of gas in than I typically would have needed. SCCA scales aren't always accurate and nothing would suck more than to get DSQ'ed for being 5 lbs underweight.

edit:

Butch is going to work with me this weekend so I can learn the procedure they use. He is going to get me the equipment so we can pull data at BW.

FHT_Racing you will get to race Joe McClughan & the other 2 Mazda2 guys. Glad SW Div is getting a few more B-Specs on track!

Yes, sir! Joe, Steve, and James I believe. It will be fun chasing them down :)
