Track prepped Rotrex Supercharged Miata

Stoptech V8r brakes are great! Need to change rear compound to something with less bite. Got some XR4's on the way.
With the 1" master and sport booster they are still a bit touchy for good heel toe blipping. Ideally I would convert to dual manual masters but that's not in the cards right now. As silly as it sounds I am gonna try adding a couple of big springs to give more pedal pressure. Pretty primal but I bet it will help.

I have no issue with standard '89' 1600 master cylinder and the 11.75" fronts with Goodwin (old) v3 rear (same size as sport I believe)..Carbotech/G-lok pads.
In fact I am scared to make any changes because they are that perfect..... but then I like a 15 and 16 mm rear sway bar too....must just be me.

Both my front and rear calipers have larger piston volumes than what you're running. It's not a great comparison.
I am serious about rigging up some springs to add pedal pressure. Kinda getto but should help with the problem till I can give it more attention.
Moving onto important things....Working on gear ratios for the new sequential. Plan to pull the trigger this week.

It's classed as SU just to make things easier as we shake out the car. I crunched the numbers and it will fit in ST2 pretty easy with some tweaks. That class is not that great in my region though. ST3-ST4 is where you want to be for good racing. ST3 looks very doable. ST4 will be tough with the non OEM roofline and pending sequential.
I need to optimize the saline interface over the next few events. That's really what's holding things back at the moment. The extra power and grip helps overcome some of that to make racing more exciting.

The time has come to part with my Miata. It's been a long fun road ending with much less usage than I expected. When I started building the ultimate track Miata I was driving 10+ times a year. Lately it's once or twice, I just don't see that changing in the future. The car is soooooo well sorted! It just needs to be driven more!

I posted it in the classified today. https://www.miataturbo.net/cars-sale...4/#post1523821
While taking photos I could not help but appreciate how well this body kit keeps air off of the tires.
The bumper extends the area of downforce from the splitter with all that flat surface area
The integrated duck tail, Smooth tapered back window and extended wing mounts all combine for great rear downforce with reasonable drag.

I have said it before (maybe even in this thread) but I love this car.
It rips me that Autokonection (sp?) couldn't stay in business with this kit. I ordered it so many times and each time bailed feeling the time lines (or something) weren't right with his payment versus orders etc. Sadly for a friend of ours who paid and never recieved.
BUT youare so right, it is a lovely kit when fitted properly like yours.
