The music I'm listening to has a big sigh noise that happened right about 0:16 in that video. It was beautifully timed.

Curbs on race tracks can be bumpy. Ride onboard with Josh Vieira from Track Monkey Apparel as he races around Virginia International Raceway (VIR) in his 1987 Porsche 944 during our 2017 Tire Rack Ultimate Track Car Challenge.

Is that shifter just sitting in a bowl of jello under the car?

I avoid all curbs with my torsen diff'd track miata,they don't like curbs much.

In reply to kevlarcorolla:

The 944's shifter base is mounted to the top of the torque tube, the linkage runs to the transaxle in the rear and the torque tube connects the engine to the transaxle.

The shifter is known to wear out due to the vibrations and the transaxle mounts aren't terribly strong and motor mounts can fail and not be easily noticed.

I suspect a refreshed linkage and shifter with a poly-filled transaxle mount and new engine mounts would go a long way to reducing that effect.

Can you describe what happens? I can vaguely imagine that it would cause a noticable symptom but i can't really figure what it is..

Looks like he hit many crub but no fents, burshes or bricks

With 650lb/in springs and sketchy Taiwanese shock valving, I generally keep off the curbs...

There was a hole at a track in Colorado I used to go to (Pueblo) where there was no curb. Apex point was dirt. That dirt wore away into a hole.

If you did it right, you could hook the inside of your tires on the edge of the track surface and gain a few mph corner speed. Really unnerving though, and if you were depending on it and missed you would be off.

And I gotta believe it was hard on the car.

In reply to Robbie:

We do the same at our ice races,its a flooded track(every week) and the non studded guys will scrub the inside bank until they uncover the raised edge of the ice under the bank.

And yes if you do it just right it works great,do it wrong and lots of bad things can happen....or you break balljoints/tie rod ends and bad things happen even if you hook it just right so ya takes yer chances.

I actually started laughing because in the first part of the video I was trying to figure out why he was being so dainty with the curbing. I pound the curbs mercilessly but I've got built suspension and a touring car driver brain.

I like my ball joints and suspension components to remain. It would b interesting to see if keeping it off the curbs and smooth is faster. Unless there is money to be had at the end I tend to think more of car preservation. I think this comes from my endurance racing background.

In stage rally they call that curb/gutter/ditch hooking, and it is bad for just about everything in the suspension. Also seen on Initial D!

The turn 3/4 combo at NJMP is like that - and when sprint racing there it's a couple 10ths worth of time. If you do it just right and gently place the tire against the inside lip it's not that hard on the car but if you come slamming into it you can bend things pretty easily. We had a for-pay driver in our enduro car ruin a wheel and unseat the tire being hamfisted with it.

If you it during an open track day though, they black flag you and yell because they don't much care for racers coming in and scaring the other drivers or throwing sand all over the track to eek out a few extra 10ths. So, you can only practice the timing in race practice. Spoilsports, the lot of them

There was a chunk of asphalt missing from the apex in Turn 9 at Willow Springs - a scary decreasing-radius turn taken at high speed. If you hit it just right and had the car loaded up, you wouldn't feel a thing because the tire flew right over the top of the missing section. I can only conclude that you guys just drive slow

Comparing a borked ball joint on a rusty old ice racer to the need to find another $800 torsen diff for the miata is apples to oranges.

The torsen diffs will spin the inside rear under power like an open diff after popping a curb,when it touches down it can 'splode.

I popped a curb at mosport yrs ago with my turbo AE86 and showed many people the complete underside of the car...never came closer to rolling without actually rolling.

So now I'm a little more reserved with curb useage.

Ken Block popped a curb on my local track and DID flip, and that was in a GRC car!

On a recent episode of Grassroots Motorsports Live, we took a rare tour of the fabled basement that lies beneath Mazda’s R&D building in Irvine, California. There we explored a treasure trove of Mazda history: prototypes, legendary race cars and show specials. And yes, there were lots of cool Miatas and RX-7 rarities.

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.
