They had a booth going at Driftcon too, seems weird they would host a C&C on the same day. On the plus side I picked up a set of seat brackets and got my seat installed, so that was fun.

 

Nice, I'm guessing you got the Planted seat brackets? I got the same I'm just waiting to order a rollbar and harnesses to go with mine

Yep, they seem pretty well made, a little heavy. I had to modify the rear floor mount point to get the bolt to line up, but otherwise no issues. I need to pick up a roll bar here soon. I wanted a BBFW, but I might just go to 425 and have them do it, it costs about the same and there's no shipping and it's fitted to me. I went with status racing 6 points, pics in my build thread. I like them, they fit great and the wider 3 inch ones are more comfortable to me.

 

You and I have the same idea lol. I'm probably going to go with a BBFW for the street cred and extra kitties xD. I'll probably do the ASM belts from Schroth with the optional sub belt

 

Schroth profi II you wont regret it. They are the most conformable harnesses i have ever used.

 

I'll probably go that route then when I get the $$$. How did you mount the sub belt/crotch strap? Is is bolted directly to the floor or did you do something different?

 

I have a piece of 3/16 flat bar bolted across the two seat brackets that i mounted the sub straps in the right place. Right now i have eyelets there but i will switch those out for flat anchor points so i can drop both seats even lower. If you do it this way make sure to use good hardware none of the cheap Chinese junk. The sub straps are hard to bolt to the floor in the correct spot because of the frame rail braces i have.

 

Yeah, Schroth is definitely a solid option. 425 showed me a piece for the sub belt, it's essentially just a steel plate with a hole and a bolt welded to it, drill through the floor pan, it mounts on the underside, belt mounting bolts screws into it. My initial thought on seeing it was that it was a weld in application, but apparently not. If I had more funds I would have had the cage extend and provide mounting points for everything, so it was all contained. As it is, I'll probably find somebody to weld a nut to a steel plate for 10 bucks and do it like the piece 425 showed me.

Edit: oh damn, I didn't even consider the frame rail there, it runs almost right under the middle of my seat. Might have to run a plate between the two mounts as well.

 

so much this. I was planning to use the backer plates they sell until i started laying everything out and had to get creative.

 

Signed up for a few local trackdays with my girlfriend, not sure if any of you will be there, but let me know if so!

Turn2 7/7
Revscene TSS 7/8
TNiA 7/20
Turn2 8/4
Revscene TSS 8/26

May add some other dates but those are the ones I'm signed up for so far.

 

I want to do a track day but I still have the Miata shake that I need to fix. Idk if it's wheel balance or something but it's getting on my nerves. Any ideas?

 

Describe it. Is it speed specific? Is it specific to one set of wheels? Did you get your wheels road force balanced?

 

From what I've read it's just inherent to the light chassis, bracing should help. I don't remember having it before any braces, but I definitely don't now with the braces haha. That said, if you do have an unbalanced wheel, an off alignment, bad bearing, or a tire issue like a thin spot or uneven wear, those would definitely be things to fix and could eliminate the problem.

 

Schwabie has Hunter RFB machines. Get your wheels and tires balanced down to like 15 lbs FTW.

 

Well the shake is worse around 60-70 mph, but I do get a slight tremor around 40 mph and up. The wheels are not RoadForce balanced, but I have some stretch on my tires, you think I could still get them balanced? I did notice an improvement with the hardtop and GS door bushings, so chassis rigidity is to an extent part of the proglem

 

That's the resonant 60mph shimmy every Miata gets. Get the road force balance. Insist on low weight. Profit.

 

I know my tires are super sensitive to balance otherwise they will vibrate the **** out of the car. Keep in mind tire balance changes as the tires wear.

 

Also does anyone in the area have a spare front bumper i can chop up to make an air dam with and still have a nice streetable one. Preferably white if possible.

 

Alright, luckily I have the next 2 days off so I can get this sorted out. Any shops you guys recommend?
