[Flyin'] Mazdaspeed Miata: First Track Test Impressions
Here is my MSM in its first trackday since the engine failure.

It's unfortunate that I have only this session to give it a good benchmark test. The IC pipe popped out and ended the day for the car since I couldn't get it to stay on. Also, I have another video of the session prior to this one to show what happens when you combine rushing to get on track, forgetting to set shock setting, colder track temps and high tire pressures; it only reeked havoc on the car's handling.
Here's my evaluation, copy and pasted from the YouTube description.
Testing for items of interest:
1. Custom-built BP4W motor w/ FM2 turbo kit
2. Falken Azenis RT-615 tires
3. FM frame rail
1. OMG, so much faster and more responsive relative to a stock-ECU MSM. But obviously, as seen on the film, I'm still no match against power cars on the straights. Note that I'm not running full boost right now because I still getting some knocking issues sorted out. As soon as that's done, I can finally turn up my boost to full power.
2. I can see what people have been on about with these tires. These have great response, awesome dry grip and warm up quickly (only took a half a lap). However, after about 5 minutes of hard driving, the tires started to get a bit greasy, but not uncontrollable. To me, this verifies the auto-x reputation, but for the track, I still think my old BFG KDW2s still come out on top on the track because they take heat better and grip better overall through long track sessions.
3. In short, even the old suspension benefited from the chassis stiffening and added to the responsiveness and stability in the corners. As a bonus, they also help the chassis cope with the bumps on the track compared to my last visit.
