Hey you should send this to some car magazine, car racing site or something. It's great!
All falkens we get here in Greece now are made in Turkey. Don't know if yours are made somewhere else but what we get is no longer made in Japan. Wish the best for next season. And keep those posts coming! |
As always a great write up. Love Gingerman. By far the track I’m best at. Hope to catch you at one of the last events this year. I probably have one more in me this fall.

And keep those posts coming! Someone else had mentioned where the Falkens were made. I'd need to check the date codes. According to some other guys, when I bought them they shouldn't have had some quality issues. But like I said, I think the chunkage was all driver error here. I definitely ranked on the wheel with hot tires and understeer. BAD!

S2 4.77 Rear End
So.. I had this thing delivered about 5 hours before we had to have the car on the trailer for Midwest. Thought about putting it on.. but I didn't want to risk it. Glad I didn't, just for my own sanity. But hey, as soon as I got back I tossed the car in the air and got to work. Slowly working on it and 3 days later it's in. The bolts for the mounting bushings didn't seize! Yay! Some photos: https://cimg9.ibsrv.net/gimg/www.rx8...da9e8b4505.jpg https://cimg7.ibsrv.net/gimg/www.rx8...b70d1d891c.jpg https://cimg8.ibsrv.net/gimg/www.rx8...0762fbad94.jpg https://cimg9.ibsrv.net/gimg/www.rx8...b4fdac7f6a.jpg Initial impressions: Heck yeah son! Definitely an upgrade on a budget, and the car has a lot more response. 4th gear shift from redline in 3rd is WAY less boggy, but definitely could be a bit shorter yet. Hard to say for sure from a single highway run at night.. but I'm definitely happy with the upgrade so far. Shifting feels like it can be faster too with less RPM drop. 10/10 would recommend. I think over the winter I may use the other axle to build up a 5.12 + Cusco/OS Giken/etc unit and see how that does. Until then, I'm super stoked to race this thing. |
do not put a pos Cusco etc. in there, get a proper OSG
you'll need an oil cooler setup for tracking on a 5.125 R&P too |
Coincidentally I asked through email that Aussie dude who makes 5.12 r&p for rx8/7s and he told me he won't be making another batch.
On the diff, I 've read on the internets that Cuscos are just rebranded Kaaz? |

Good call on an upgraded oil cooler though, didn't think of that immediately as a need, but makes sense.

Maybe he'll reconsider? Or find a used one?
osg diffs can take a beating. Don't know if those made now are made with the same resources as the older ones but maybe I'm just the "they made it better back in the day" dude. They surely seem more robust than competition with a 40% premium on price. |
Pad slapped some XP12 yesterday, actually thought the pads were lower than they were. Ah well, good backups! This is 1.5 seasons of use, VERY mild street use.
https://cimg1.ibsrv.net/gimg/www.rx8...a4f5caa027.jpg https://cimg2.ibsrv.net/gimg/www.rx8...5f1d174628.jpg Some other fun notes on inspection of the car: At Gingerman last time I was there I had this odd grinding noise ONLY when hitting the brakes in reverse.. never was a problem on track so I just said whatever and kept going. Came to find the top caliper bolt was not existent anymore. WHOOPS. But that allowed the caliper to rotate when reverse. Real sketchy, let's try to not do that again. Trying to get to at least one more event before the snow starts blowing in... looks like it's either next weekend or that's it... we will see. |
Don't really want to self promote too much, but figured I'd leave it here for anyone reading this, or stumbling upon it with a google search.
I developed a controller that you can use to plug into the OEM Mazda RX-8 EPS controller that allows the EPS to act standalone from the rest of the system. 4 wires, and you're done. I like making boards, so here's one that looks cool and does a job! https://cimg3.ibsrv.net/gimg/www.rx8...47016d7610.png If anyone wants more details, just let me direct you away from this website.. which is exactly what websites hate haha: www.facebook.com/GROMElectronics |
Is this a good thing ? Please explain why you would want to do that.

Not me, specifically, but anyone without a factory ECM, or a different manufacturers ECM would require something like this

This is definitely up the my alley, but it's tricky:
Power steering: Solved, haha. ECMs: I can program ECUs to work with the immobilizer your car is tethered too.. however it's basically just a hardware clone, not a full disable. Just need a copy of 1 of the ECUs and then you can program as many other ECUs as you'd like. Dash/clusters aren't tethered to the vehicle, but are driven by factory CAN signals. I have reversed engineered most of the cluster functionality and can drive it.. however getting those actual inputs from people's vehicles is different since every engine/controller has a different way of broadcasting metrics. Creating something that caters to everyone is hard, and creating something that caters to the exact 3 people with an engine/chassis combo is expensive ABS: Just unplug the unit, haha! |

Season Wrap-up Post + Winter Plans
Figured I'd make a post about the season since it's getting cold here in Michigan, which means tires comes inside and https://cimg1.ibsrv.net/gimg/www.rx8...29cdede807.png Ended up 16/37 and managed to scrape up a decent amount of points at each event. Seeing as points are based off the time of the winner, being in 16th with the rest of the pack almost half of my point behind feels like it was an all around good drive, and not a single track ringer. Solid mid pack, and I'm happy with it. On to the good and bad. The good:
On to winter work:
Super exciting to dig more into this thing and get back on the track soon. Until then, it's time to throw snow tires on my STi hatch and practice my Scandinavian flicks while bitching about traffic until spring when I can only bitch about traffic. |
No issues with OEM rear calipers for me even with ST43s so I assume it's the parts store calipers at fault. New OEM are kinda pricey but at least the OEM seals are cheap and readily available and no heat issues.
Agreed, the RX-8 will never make enough power to be competitive in Club TR. Sucks, but it is what it is. Series 2 fuel pump/surge tank thingy is a pretty easy upgrade and I can run mine down until the light comes on. I'm hoping to do Pocono & NJMP next year but we'll see :) |
Sunroof Delete - It's going. I'm going to try to make my own carbon fiber plug... we will see how that goes. Sounds like another $1000 Garrett endeavor with results that don't matter Mazda RX-8 dry carbon roof / Marsh Composites Hope everything goes smoothly during winter. |

There was a guy here who replaced the roof panel with a dry cc one. If you're thinking of 1k, might worth checking out if they still produce.

I've always wanted to mess around with carbon fiber stuff, and this is a good excuse to give it a shot. I've got some good tips from my brother (Aero engineer who's hand laid carbon for airfoils before), so I think I can manage a roof plug :shrug:. Always willing to waste money if I learn something, even if the end product sucks a bit. |

Pretty simple take old off and put new in. If you rear end bushings are in bad shape and seized up so you can loosen stuff up, it'll be a huuuuge pain to get the rear axles in/out. Best advice I've got.

Agency Power Midpipe
Nothing too wild here, found a midpipe that seemed like it made more sense to have so I slapped it in. Honestly, the best part about it was just having new hardware and gaskets that aren't rusted. More powah to be had? Probably not. https://cimg6.ibsrv.net/gimg/www.rx8...42f504d8c8.jpg While I was under the car, I also did see one of the trans sensors leaking from the interface to the case. Gave it a nice jerk to see if compressing the crush washer more fixes it. https://cimg4.ibsrv.net/gimg/www.rx8...25b2921673.jpg Unrelated sidenote: Winter has finally come. The weather is cold, but the shop is warm. Subaru with snow tires is essential for keeping moral up. Gonna be a dark few months boys and girls. https://cimg5.ibsrv.net/gimg/www.rx8...a0ef4c4947.jpg |
might look closer next time to make sure it’s not leaking from the potting at the wiring end and drizzling to the case; common issue with that sensor.
|
Was browsing ebay and saw that the Aussie dude who made 5.1, 5.3 r&p for RX8s has stock up for sale.
