Selling my '99 Miata, it's currently slotted into csp, but could probably be run locally in str without issues. Some of the work done on it:
'05 engine block with a refurbished '99 head that was put on about 3 years ago (which is why it's in csp)
RB front sway bar
RB cai
Rear Koni yellow's were replaced in the spring of '21
Fronts are Koni race's
I believe the springs are the Eibach set, something like 650lbs in the front, 400lbs in the back or about that.
225/45/15 Rival's are currently on it with lots of tread, but the tires have heat cycled out a bit.
Clutch is low mileage
Exedy lightweight flywheel
The car is a California model, but the goofy cali 2nd cat/header has been removed and replaced with a standard header. It still has the cali ecu in it, but I do have a 49 state ecu you can drop in it.
The downside, the car does have a salvage title. It was in a front end collision before I bought it, the front driver's side suspension was completely replaced. Car drives perfectly though, you can't tell there was ever anything done to it. It also needs a new top. It's currently water tight, but there is tape covering the holes.
The car has a history in the club, so there are a number of people who can vouch for how it drives. Let me know if you have any quesitons or want more info!
