When I talked to you at Mid-O you mentioned she cut-out and wouldn't re-fire. You figure out the issues yet?
While the K motor itself is wonderfully reliable and makes easy power, K Miatas products are not the highest quality in my experience. Justin Lee has a K Miata trans kit in the WRL V6 car and at Mid-O last October we were fighting issues with driveline vibration and sloppy driveshaft joints that ate 3 output shaft seals and stripped out the adapter piece. Not to mention the numerous issues Greg Peters has had on his car.
I have a K-Miata BMW trans kit and have no problems with the custom driveshaft. It was made by a driveshaft shop and isn't something made in house by them according to the packaging.
Sometimes outside suppliers get it wrong, so taking it to a local driveshaft shop to have the balance and components checked would have been on my list after first indication of trouble. Even brand new u-joints can fail.
I had good responses out of them for every question I had.
Toyo RR is added to the 100tw category and therefore gets a +.5 credit and is available in 245/40/15. That becomes pretty attractive.
I am considering 225/45 RR on 9" for less contested events/practice setup as it "pays for" my splitter(-.5). That lets me run at 150/2265 with splitter/wing at my current power.
Using 205 R7 on an 8" requires me to add 75lbs(at 150avg whp)
I took a few months off Miata-ing from NASA Champs until after New Years. Felt good to disconnect from this car for a while, and I feel recharged for 2020 efforts.
Keegan Engineering is going to help get the engine package up to GLTC power level. So I pulled the lump and it’s leaving today.
I’m still focusing primarily on NASA ST5/TT5 for 2020, but will be making a couple mods that take penalties in that ruleset so the car is better for GLTC and just fun local HPDE stuff with friends.
Unless the stars align, I won’t be making the tow to Utah, so Miata Reunion is probably my farthest travel plan.
2020 Goals:
-Sub 1:37 Mid Ohio Club Course N/A BP
-Drive VIR again
-Drive Road Atlanta for the first time.
-Sweet new Tarmac 88 livery.

Presuambly you are aware they had a problem in the first batch or so with one of the pieces in the kit?
I had unreal (read frghtening) vibration and got sent a replacement part. Between that and a drive shaft balance it has mostly gone away now.
I too found them incredibly helpfull and very keen to work through any issues. Coudln't recommend them enough.
What kind of power are you aiming for in GLTC trim? I know most of the Miatas are running (or swaping to) K24's. A few dumb people (Cody and I) are sticking to low boost BP's.

~165 peak is my target for ST5's 158 average power at 2450lbs.
I plan on running a splitter, and pulling all 250lbs of NASA ballast out, so it will be a very light(~2180) car on 205s, probably.
I’m undecided on the headlights. I have satin black for them like the “rendering”, but covering them with the white/color gradient would also be cool.
I have to make a decision on the build plan concerning splitter vs airdam-only, before I wrap one of the airdams.
I’ve wrapped a few commercial vans/trucks in my past, but never worked with panels this large on such a curvy car before. So I’m learning a ton as I go.
The rear bumper and hardtop will likely get 3-4 pieces with seams. They’ll both have two colors, and each color with need two pieces.
