I don't think @Black Boss and the rest of the GT350 guys should have ALL the fun, so I wanted to let you guys know that my "Build Your Own Stargate" kit arrived today from Paul Faessler at Paul's Automotive Engineering. Just waiting on the hats and then I can get this stuff on the car!

Looking great. If I didn't have the 350 coming, front brakes would have been my next upgrade. Love the thickness of those pads

Paul is a great source and does great work, buddy of mine had him upgrade his Fox Body track car, including a Coyote 8)

Dude,
your brakes can beat up everyone's ;D brakes.....

Very cool. 15's from the 2014 302S (same kit, I mean)?

Bingo.

Started installing the 13" rear kit from FTBR today also.

 

[302 Hi Pro]

Drew:

The new Brembo brake setup is like art work! Just leave it as is on the coffee table.

Nice, very nice.

Dave,

I enjoy your updates via my email notifications...but I gotta check in more often for all the awesome pics. Congrats on a successful 2015 season!

 

[Greg Obadia]

Paul is a great resource. Nice choice on the fronts.

Updated 2015 season stats--totally forgot the Halloween event due to an error in my spreadsheet:

I know those host thick 25mm pads, but how does the pad shape compare to the stock Brembo calipers in terms of pad-to-rotor surface area?

I had the same question after seeing @Black Boss 's photos of the GT530 pads vs. the Boss Brembo Pads.

The pad shape for the race calipers is 7770, and compared to the 7781s (OEM Brembos) the race pads are slightly shorter height wise, but slightly longer width wise. I'd wager the swept area is roughly equal between the two pads.

OK, got the hats in last night and installed everything. Tight fit with the PF01s but they do clear!

That is a tight fit but that is all you need. I have been running these brakes for the last year and have been very pleased. It is vice having the 25mm thick pads.

Nice, how many mm clearance do you have?

 

[ls110]

Nice, how many mm clearance do you have?

Not sure of total clearance. Running Vorshlag Forgestar F14s and from the photo, guessing I may have 1 mm more clearance, although very close.

 

[ArizonaBOSS]

Nice, how many mm clearance do you have?

Probably 3mm or so--more than I thought would exist. I am also running a 1/2" spacer up front that pushes the wheel out a bit so the caliper is in the wider part of the barrel, but they clear fine without any spacer as well, to my pleasant surprise.

Thats what she said HAHAHAHAHAHAHHAHHAHA

OK weekend report from our 2016 season-opener...it was a rollercoaster of a weekend.

On Friday I got the car over to the dyno, and encountered a similar situation to what @Tucson302 noted in his Time Trial thread--my car read a bit lower than I expected. My best runs were down about 15hp and 10tq across the entire rev range after installing the Kooks headers. I previously had 410whp on this same dyno in very similar weather conditions, but now she only put down 395. I was expecting something in the 420-435hp range, so needless to say I was very confused. I don't think these numbers were accurate as I've seen this install on many B302s and every single one gained power.

Saturday's practice session went well and I was pleased to have no issues whatsoever with the new brake package. I did remove the 1/2" spacers up front and switch back to my original 1/4" spacers as there looked to be some tire rub after practice. The car certainly didn't feel down on power, and I was able to reach the same speeds at the ends of the straights despite over-slowing into corners with the new brake package. I am thinking even more that I just got some weird data at the dyno. I'll go back in a couple months to check again. No CELs or knock, AFR looks solid.

During qualifying I put the car on the pole for the race group and ran just shy of a personal best time at this track (Wild Horse Pass East).
I got a great start during the race and gapped the field by about half a lap.

Unfortunately, in Lap 10 of 24 I made a bad decision when passing lap traffic and punted another car off the track. That took the other car out of the race and left my steering angled when traveling straight ahead. I was ashamed by my stupidity. That combined with the damage to the steering prompted me to retire from Saturday's race. The collision also bent both of my driver's side wheels, dented my door and rear quarter and front fender. I was able to massage the front fender back into shape but the door and quarter will have to wait until summer. Fortunately the door still opens and closes just fine. The driver of the car I punted talked for about 20 mins and I am working with him now to make sure he will be ready to run next month's event.

Filling out Body Contact Report (BCR) forms:

I expected the steering issue to be a bent inner tie rod for sure, but they were completely undamaged. I was very confused. Then I noticed the driver's ball joint APPEARED to be bent. I removed it (thankfully I have Watson-ized my LCAs and ball joints) and sure enough it was pretty badly bent. Fortunately, I carry a spare ball joint and within 20 mins the BJ was replaced and the steering was confirmed straight! The rear axle was a bit pushed over from the impact by about 1/4" so I will have to tackle that later. We took the A7s off the car and put on the practice set of wheels with R7s for Sunday.

Sunday morning I was able to shake the car down in the practice session and everything (thankfully) felt great, at least good enough to race.
During qualifying I was again able to put the car on pole despite the incidents and damage, but there were some ST3 cars within a couple tenths of my time.

I ended up getting a great jump at the start and pulled away again! This time I was much more conservative moving through lap traffic. The race ended about 3 minutes early under red flag conditions after one of the guys in my class blew an engine and put oil down on the track, but I took the overall victory!

I wasn't planning to run Time Trial this weekend but decided to do it and try and win a couple tires to offset some of my damage costs from the weekend. I had to butt in on @Tucson302 's victory on Sunday by doing so but will be more respectful of that for the remainder of the season. We did get the opportunity to do some lead/follow laps together after I laid down a couple 10/10ths laps for tires.

Things were looking up! At least until I was loading the car into the trailer. I caught the splitter on the door of the trailer and the splitter shattered into about 30 pieces.

@captdistraction and I are getting ready to make some locally here as replacements and she'll be back to normal in a couple weeks; I have ordered some Race Ramps as well.

Not the weekend I was hoping for but the brake package did work out great. Everything about the car worked out great, really--just not the driver.

That's racing!

 

[Tucson 302]

Well done my friend! You didn't butt in, its competition! I just need to get faster and doing the lead/follow definitely helped, so hopefully when we go back to East in March I can drop a second or two.

 

[VoodooBoss]

Great update and good luck with the repairs. Are you financially responsible for the damage to the other car?

I am not liable for the damages due to the "no fault accident" rule, but I am going to cover a bunch of the damages anyways plus his entry fee for the next event since it was completely my fault. Probably in it for about $1K or less. Sucks but it was my decision that caused it and I don't want him to be not racing because of my dumb decision. If it were a mutual collision then I would not offer to pick any of it up.
