OOO, i love this question. This car is on the ORIGINAL (90k+ miles) engine. Primary power adders are some minor air box mods, rx8performance underdrive pulleys (mostly to keep water pump from cavitating and to keep alternator from frying), catback exhaust, and custom versatuner tune. otherwise it's an old but seemingly healthy engine (at least above 3,000 rpms).

@@rx8matt wow original motor a surprise! best of luck

@@rx8matt Beat me to it! I wanted to ask about reliability modifications...good stuff there!

@@drewniakj basically, cooling upgrades, and slightly increased omp rates, and idemitsu premix at track, and good maintenance

I wonder if 100 ft-lbs of torque in the midrange would help or hinder considering the first two car types?

@@charleshuffman6982 i wouldn't mind an extra 100 lb-ft of torque - i think i could put it to good use!

i think you snapped that picture, i just cropped it down. Thanks. 1:50 was a little too hot and a little too late on the brake release and a little too slow getting back to maintenance throttle to stabilize the car during turn-in. had i opened up the throttle sooner i think i could've avoided the slide.

F street. I feel like that PAX is broken! But the driver is a national champion and spares few expenses so maybe not

@@rx8matt 100%! it's impossible to win PAX in anything other than a stock ("street" class) car (assuming any good drivers are running)

if you google "rx8 fujitsubo exhaust" there appears to be a few vendors carrying it. here's one on ebay: www.ebay.com/itm/192298568003

it's very quiet and doesn't save much weight over stock and is very expensive so i'd honestly recommend hks legamax or racing beat duals.

about 13-9/16" ride height front and rear (call it 13.5"). Maximum settings for front camber and caster, rear camber matches the front. i don't even know the exact numbers as i do it in my garage, i just want to ensure i have side-to-side and front-to-rear consistency. i would assume the camber is high 2s, low 3s. i run zero toe all around for good street tire wear and less straight-line drag at circuits. That's a bit spicey, if i didn't care about tire wear i'd probably use +1/16" total rear toe in, and i'd probably be anywhere from -1/16" to -1/8" total front toe out for autocross and corner-intensive circuits.

Mazda DEFINITELY was focused on building a track-competent sportscar... but one that is still very comfortable on the street.

Thanks Brian. Well, the auto provides an excellent opportunity for left for braking. That's how I got my start (automatic on street), then I used it in rallycross, then at autocross and finally TT

Very true.. I tried going down that path years ago, but was still quicker right foot braking. I knew if I wanted to do LFB, I'd have to sacrifice at least a year of practice to match my RFB abilities. I've been too stubborn and competitive to give up the speed now for speed later.. I'll use your foot cam vids for the inspiration to change! 🙂

Thanks Meyer. Right foot is fine during heel toe braking but when I'm not shifting left foot is the go-to. It's not bad for 90,000 miles. It sucks below 3,000 rpms at low speed corner exit digs but it boils on top end.

Thanks man. I've been very envious of your fast courses... We're still not in the same league but this was a nice change of (literal) pace.

@@rx8matt heading back to the local road course autoX this Saturday, hoping my new camera arrives before then ...🤞

@@BushidoDriver looking forward to it!

Thanks man. Never know what people will think... But since I make my videos mostly for my own amusement, it seemed like a good match! 😁

Thanks man... I was really disappointed with myself this event because I could have been P2 overall vice P5 if I put it all together. But I went fast and had fun and the raw pace in most places was solid.

It was more like "damn, I'm losing a bunch of time and wasting rubber... But I bet I look cool..."

Thanks man. yeah the OEM rx8 are one of the few known weak points in the car. The flex a lite FAL420 fan kit isn't a bolt-on affair, but you can get creative with mounting and it's a REALLY good upgrade. no more overheating in traffic, even in summer with full A/C on.

glad at least one poor soul out there enjoys my tastes! 😄

Thanks. i think it helps me most of the time, but in a few runs i think i was using the pedals TOO much to turn the car. throwback to my rallycross days. i may need to calm it down a hair in places and just use steering and tire scrub for speed control like the people with infinite tire budgets do.

@@rx8matt we just got a new site that's pretty tight (relative to what I've run the past few seasons) on top of having a slick concrete pad in the center. I never had to think about helping the car to rotate before (...or not shifting out of second for that matter 🤣) now its a Different story. #AdaptAndOvercome

@@BushidoDriver ah, the Monaco of autocross! Many of our venues are smaller so I feel your pain

not obvious in video, but it was slightly downhill and i was rolling towards the start beam. maybe that wouldn't have been a bad thing!

for sure! i think they can strike an awesome balance between daily practicality and comfort and speed and reward at the track. welcome to the club!

heat 1 was for sure nerfed by the water and dirty track. heat 3 was really hot and the finish line area started to disintegrate. i honestly think heat 2 had it best, the top finishing STX car went 0.5 seconds faster in heat 2 than heat 3 even with the extra seat time.

I pondered that same question. 4.5 degrees of negative camber, low ride height, and A052s certainly played a role. also the FRS appears to have an acceleration edge on my tired RX-8. That said, cody entered the double-right 90 turn better than me, in an almost motorcycle-like line. and i overslowed a bit in the last right before finish. i am pretty happy with my 43.1 but there's always room for improvement. i use VideoPad for the final compilation. racerender and dashware for data and general splitscreens.

Low power momentum car I guess. I dunno man, I think I had the course read wrong in a few places. Oh well

Perhaps the best handling production car of all time. 🤘🤘

What mods to this chassis set up Matt? You running stiffer sway bars? It's very balanced​@@rx8matt

@@darrenlucas2768 I was on fortune auto coilovers and a bigger front swaybar. Nothing crazy! My current blue car handles the best out of either of them on Ohlins

@@rx8matt do you think it only needs a stiffer front sway bar,and standard rear?

@@darrenlucas2768 That's what i run. autocrossers who like lots of transitional stability often run no rear bar. i have played around with no rear bar, fast in slaloms but suffer in sweepers and in corner exits. track guys ith aero or non-traditional spring ratios might run a slightly stiffer rear bar.

Yeah I plan to make almost all of the PCA chesapeake, MBCA and SCCA events in DC. Come say hi next time, I'll be happy to chat

They wanted to add to the, erm, "challenge". 😉😉

Sadly, for as awesome as it looks and as fast as it felt... when i looked at the data, it was a really minor difference (<0.1 sec). so it's certainly not worth the risk of mis-shift and the synchro wear and tear. it FELT fast AF, but stopwatch says let the car bog and just try to keep up mid-corner speed (and rpm). every time i try a first gear downshift and then look at the data, there's not much difference. but if you're up for a challenge it certainly adds to the fun.

Yeah, aka I should've used a small lift and kept my darn feet off the brakes! I'll look at my data this afternoon to see how much I lost right there. This was my first go pro event, I was troubleshooting battery issues and didn't have time to play with settings prior. I'm going to zoom out for next event. Ps... Can't wait to see you almost FTD run on video

@@rx8matt The very last corner really did not require brakes. I gained half a second by just lifting and being patient on throttle. Car was more stable too. My video is up with data. Looking at the traction circle looks like your car had a slight edge in braking grip. Maybe I've just got too much front camber. I struggled to make the stop box. Nice to see we were both easily pulling 1G in the wet. Bowie is very fast and planted in the wet.

He lifted off the throttle on the straight to let me by because my overall lap times were faster. It's part of courteous one-track behavior. Both better were definitely quicker on the straights when they weren't giving a "point-by"

Dicey to say the least! Other circuits aren't so bad

Fal420 fans, higher water percentage, higher pressure cap, undersize water pump pulley, earlier fan activation. No overheating

@@rx8matt Thanks a lot for the response, gonna check out the fal420 fans and pulley. What method did you use to get the fans to kick on earlier?

@@arespy719 versatuner programming

Don't forget to comment on Curt's and Dad's videos too!

Just picked up a go pro 9, now I'll have higher quality dash and foot cam. But might want to find a POV where you can see my hands.

Really like the helmet mount so I can see my hand movement as well as head movement, or in my case lack thereof.

@@GTI_Autocross agree, I gotta get an adapter to put new go pro on helmet or perhaps over shoulder

@rx8matt I bought a whole bunch from Amazon. Happy to give you some next time I see you

@@GTI_Autocross dang, yeah I'll take you up on that offer. Thanks!

it didn't hurt me as much as i thought it did, but yeah still lost a little time. probably gathered it up best i could.

Yah, im responding from my other channel lol but in my RX8 on certain tracks there's turns like 11 at LagunaSeca if you do a low angle slide on entry and just stand on it in apex you get a slight countersteer exit but the RPM stays up right at the point that it needs to be to be in powerband to run up the straight. Terrible on tire life, lol but there's no amount of quarters at any arcade that produces more fun.

Are there no organizations offering amateur track day opportunities up there?

@@rx8matt not in my part of Canada (Saskatchewan) sadly :/
