Well this thread is going straight in line with where I'm at too. Hacked the rear fenders out for the flares yesterday... have 5 9"ULs pre-ordered (always have a spare). I just wish I had some 275s to mount to make sure I have the clearance, but since I don't, I'm taking as much out as I can and still be able mount the flares.

Back to the splitter... is there some magic formula/ratio for splitter 'projection' (ie 1-4") surface area to rear wing area? I hear you can run with the rear wing alone, but don't want to run a splitter by itself. Put the 2 on and how do you know you have the 'right' splitter:wing ratio?

It's not really a matter of area - you make the splitter as big as possible in order to utilize the most rear downforce while still maintaining a neutral balance. Wings are adjustable, splitters generally aren't.

Here is the thread where I hacked up my fenders and installed flares.

I did extensive articulation studies with the springs removed from my shocks. The 15X9 6UL’s with 275/35’s I felt needed 15mm spacers for enough bump clearance on the inside edge both front and rear.

Last weekend I installed a 6 speed. And a 1" 929 master cylinder. I still need some additions to my splitter spats, dive planes, canards or whatever you want to call them I am still working out some DIY designs.

Anyhow, I wanted to say hi. I was at the track event hosted by Team Miata 2 years ago * i think* at Reno-Fernley. I think we were the few people from Washington state that made it down there. I was in my ls1 240sx. I was so cheering you on as you had your way with that Ferrari 430. He wasn't a slow driver from watching from the hot pits. Looked like a fun battle. In the last year, I lost my miata virginity and realized how much of an amazing car it was. In hindsight, wish I had a chance to talk to you then. I should hopefully develop a miata for lapping days this upcoming season.

Yea that was a fun event. I think It was my forth of 7 5 speed transmissions that I broke late in the day Saturday and found a replacement at a local salvage yard had it at the track by 5pm and had it in the car working by myself in the pits with my wife handing me tools by 8pm Ran the next day with it and drove it the 800 miles home on Monday. Broke transmission again two weeks later at an autocross.

The car wasn’t running good due to boost issues. The waste gate door was catching and staying open so the car was incredibly laggy but it was still dam fast when it was spooled. Learned a lesson about waste gate porting on that one.

What materials did you use for that? I ordered some 1/8" Black ABS and was looking to make something very similar for the ends in front of the front tires. I was thinking about to getting some of the cheap Ebay canards as well.

splitter - it is a material we source locally. they use this same material for building containers for military. ~$180 for a sheet of 5x8 (not 4x8), 5/8" thick. it is corrugated plastic. they come in different thickness.

canard - it is just same material you use. 1/8" ABS plastic. top piece is aluminum.

Since I have not used those materials. I am going to assume that you have. However I would think that they would react the same way the other plastics would in the event that they make contact with a burm or other surface.

I would aslo venture to say if someone has used it here that they would have mentioned it by now. I would love to find out how they hold up. If you can do it reasonably please do it and let us know how if works. That would be a great help to us all.

Have a great day,
Jared

Significantly heavier than plywood maybe a bit stiffer than ABS. I suspect the corrugated plastic bellwilliam is using is some good lightweight stuff. I couldn’t find anything like that readily available.

There's lighter stuff out there, if you want to spend between 4 and 10 times the cost of plywood.

I built a splitter for someone else on here that's basically identical to mine. He went off at Buttonwillow in December and tore the splitter off the car. The wood survived being torn off, and run over. He's building a new aluminum frame for it and bolting it back onto the car. It doesn't get more durable than that.

Here's the splitter I ran over and fixed up along with the old mounting bracket. It needs another coat of paint to hide the primer, but it mounts up just fine.
