Ever Wanted to Put a Sequential Gearbox in Your Mazda MX-5?

Long Road Racing brought a modified MX-5 to our Tire Rack Ultimate Track Car Challenge. They took a car being prepared for the Battery Tender Global MX-5 Cup presented by BFGoodrich Tires off the line and added a sequential gearbox and a few other goodies. Their lap time? 2:07.856. That’s an extremely good time for an MX-5 at Virginia International Raceway. Ride with Mazda factory driver Tom Long around VIR.

Watch The Fastest Lap Ever Recorded at the UTCC

Eric Foss came to the Tire Rack Ultimate Track Car Challenge this past weekend armed with a 630-horsepower BMW V10-powered Riley Track Day Car owned by Jeff Mosing—the guy who bought our rotary Miata project. Watch as Eric squeezes all the speed he can out of the Riley. He set a 1:44.376 lap time in his second timed session. That was the fastest time we’ve ever recorded at the Tire Rack Ultimate Track Car Challenge.

Yep, Eric can drive.

I first met Eric back at one of the first resurrected ARRCs--pretty sure it was 1995. He was driving an ITB Volvo 142. At the time, that was one of the hot cars.

Nice to see him still out there. If you're at a pro race and see Eric, stop and say hi. You can tell him that I sent you.

That's an...unusual shifting technique. Could use some more clutch on the 4th-5th shifts.

In reply to GameboyRMH:

It helps to avoid the dreaded "money shift" on the M3 by ensuring you move it to the right.

Plus, the shifter isn't in the greatest location for her shorter stature, I'd likely suggest a modified shift lever that was bent to fall more closely to hand for her.

I think you've got it. A lot of five and six speed transmissions will teach you to use something other than the classic Bondurant approved open palm technique. I shift Spec Miatas by grabbing the whole shifter with my with my thumb up against the knob and shifting with my wrist. It's fractionally slower but I get it in the correct gear every time. A Miata in good condition will survive grabbing first instead of third or second instead of fourth but it's tough on your lap times and in traffic can be detrimental to the condition of your back bumper cover.

Oh hai! I indeed have an unorthodox method of finding fifth gear. When I first got the car, I found third instead of fifth a few times. What a horrid noise! I caught it pretty quick those times, but it rattled me into changing my shifting. I didn't know any better back then and kept driving the car as it seemed okay. Probably the root cause of the valve drop last month haha. RIP S52.

I used the method APEowner described and it eventually evolved into whatever weird thing is happening now. Despite being wonky looking, it works, so I'll stick with it.

Hey Christina! I'm glad you chimed in, and not just because its a rare moment when a women (or really, anyone) says that I'm right. I predict that now that it's been made famous on the internet all of the other M3 drivers are going to be emulating your technique without knowing why. It'll be like the Valentino Rossi leg wave. Someone will be asked why they do it and they'll say "I don't know, Christina Lam does it so it must be fast" and everyone will nod knowingly.

Great battle at the beginning of the race- and given some of the threads here about racers not exactly behaving, it was also nice to see both of you give room when either of you could have easily done an F1 and force the other closer to the edge of the track.

Also hope you are a next Randy Pobst- starting as a hobbist driver, and then making fast progress up the ladder. Can't be that easy to field your own car like that.

Good luck! I ran out of guts on the track. Autocrossing was as far as my nerve would really take me.

No ABS. Yet. Looking into options to put in the E46 M3 ABS as a standalone. The mk60 system in the later model E46's is very sought after. I'll be leaving the M3 at home for Hyperfest. :( Rather put the money towards a solution vs eating tires. Hopefully it will make Pittsburgh and NJMP that much faster next month. :)

Thanks! The start is always exciting, and we had clean racing throughout the weekend. Looking for a bit more pace, and hopefully we can have some good battles this year. The guys in NASA NE's GTS2 group are fantastic on and off track. It really helps when you are friends with your competitors.

Sunday's race start was not as great. I got past the guy in front of me, and then got greedy into T1, locked it up and got sideways. Scared the guy behind pretty bad. Went and apologized to the guy afterwards and we shook hands. I'll be more careful in the future.

Next Randy Pobst! Thats a high bar! But it is the dream. I'll admit, when I did my first autox, I never imagined that I'd do HPDE. And when I did my first HPDE, I didn't think I had what it took to instruct or race. Bit by bit I'm making progress with myself and helping others. I've got a long ways to go, but I won't be stopping anytime soon.

That car showed up at an Atlanta region autocross not too long ago. It was FAST. Like trading times with Matt Glagola's modified Elise fast. IIRC I'm pretty sure Glagola eventually go FTD, but the bunny still took PAX. It was definitely fun to watch.

These are the cars that I really enjoy watching. The "unusual" cars that somebody has taken the time to sort and wrench on until they are way faster than expected. I know rabbits can be quick but when was the last time you saw one this competitive?

Any tech info? I suspect by the "good car" comment at the end that any set up info is probably highly classified within the lambobunny organization but you never know.

I've been watching that car run since I started autocrossing. It's stupid quick.

Zimmer drilling holes in things is a standing joke around here. I'm pretty sure there isn't a piece on that car that doesn't have holes drilled in it to lighten it up as much as possible.

There are a handful of guys that have done amazing things to the rabbits over the years. What is most interesting is the opposite ends of the spectrum the fast guys exist on. Typical spring rates are 400-600lbs on a sub1800 lb beast. I'm running 400f and 550R nut sadly the driver is the weak link.

He always does a great job in these videos. And I've enjoyed his 944 pics often. I dipped my celica about three years ago now. I often here people say "it doesn't last" or "it doesn't come off easy". All lies. The part they always leave out is that they didn't put it on right. .

Years ago I attended a SVT Owners open track event and met a guy who owned/built chassis #3 that Factory Five built of the Type 65 Coupe. I loved it then and love it even more now. In the 14 years since then they have improved the car quite a bit. Here's hoping I finally get the shop space to build one of there cars.
