I bought my first Miata a few months ago. Its been an absolute blast so far. My other car is a 360 HP GTI which is FWD, heavier and has flappy paddles. I wanted a car that was a complete contrast and the Miata has been amazing. RWD, incredible handling, low center of gravity and a really connected feeling to both the car and the road.
I'm setting this up for a mix of local driving and track use. Because I live close to work and don't need to make long commutes I'm planning for a fairly aggressive street setup.
My Miata is a 2002 LS. So far I've done the foamectomy, and replaced the door handle with a strap, both of which were sorely needed as I'm 6'3". I've also ordered a 330mm Nardi deep corn wheel and Ultrashield rally sport seat which hopefully will make the car truly comfortable.
Other things I've done over the past week are put on some 15x9 Racing Storm wheels with Ventus R-S3 tires. The car came with Stance coilovers and with a little tuning of the damping rates these are settling in great.
Sent the hard top off to Maaco today to get it matched to the body, and changed oil and spark plugs which has made a big difference.
