Nice! Those Miatas are a pain aren't they?
You don't know the half of it: they really play rough on the track and our Race Chair often has to yell at them. But they're also a likeable bunch. One Miata cut me off in a ridiculous pass last year that nearly sent me into a fence.....but then after the race he came up and apoligized, and gave me a big hug (the apology would have been enough!). Another Miata made a "rough pass"and banged a different Sprite that I was running in a 4 hour enduro (my buddy was driving at the time). Bent the shock and lower arm and killed our chances of a win (it was Index Of Performance event and we were running first). Our flaggers call the Spec Miatas "Special Ed Miatas". We started a new class this year so they could run in their own races....let them "nerf" against each other. Personally, I hate following them into a turn, because a lot of them stand on the brakes (much better brakes than I have) and I've nearly tapped them as a result. By the way, I don't hate Miatas. My street car is a '00 Miata....but they are the Devil's Spawn on the track!
Your car leans a bit, do you have slicks or is your suspension set a little softer so its good for wet or dry?....
Yes, Nial, I'd been meaning to ask what your suspension setup was, and how did you fit Kumhos into those rear wheel wells? What size wheel and tire are you using.....
It leans a lot!
I'm just a club racer with a mostly stock car that has some low-cost mods.
Car has orignal lever shocks in front but with no shock valves.....I am running add-on Monroe tube-type gas shocks ($17 each plus some home built brackets).
Rear lever shocks have been replaced with tubes also (easy to do....just flip the lower brackets).
I am running a 5/8" modified sway bar in the front (shorter arms to stiffen it). It was free. I would like a 7/8" bar but 3/4" would be OK for the street.
I have a 3/4" rear sway bar but do not have it installed....the car is tail-happy enough as is! I would put it on if I get a biggeer front bar.
All plastic bushings in suspension.
I built a panhard rod using some low-cost rod ends from Summit Racing...works well and cost about $20. MiniMania sells a semi-panhard rod, but I like mine better.
Front springs are stock (the heavier rubber bumper car springs) and have 1.5 coils cut out of them. They're also dropped an inch in the lower arm, with spacers.
Rear leafs have 3 extra stock leaves (held together with hose clamps).
Tires are DOT-legal Kuhmo 175/60-13. These are quasi-street tires that are also vintage-legal. About $85 at Tire Rack (I bought 6 last year, ran 11 events and 3 are still good....I just bought 2 more). I have them shaved to half depth locally by a friend. Hoosiers are better but they are also about $130 each.
For clearance on my '78 chassis, I "radiused" the rear fenders (so they look like a 1973 Midget). I also have 1/8" wheel spacers to keep the Kumhos from rubbing the springs. Stock wheels and lugs. I may switch to Chevy Vega rims and bigger lugs next year.
The car is soft but that's not really bad...Lime Rock and Pocono are pretty rough tracks.
One of my fellow Sprite racers took pickup truck springs and cut them *length wise* (down to a 1-5/8" width) , to use for the rear of his car. The car is so stiff I can't make it move when I sit on the fender. I think he has 500 inch springs in the front. When the car goes through a turn, his front wheel lifts about 3 inchs (like an old Cortina). I would have no filling left in my teeth if I drove that thing (he's 67...maybe he doesn't have any teeth).
philman:
Cool to see a '68 RoadRunner at an autocross....smokey burnouts!
I'm off to a two-day race and enduro at BeaveRun (PA) tonight....gotta go back and load up the truck now.
