Hey everyone,

Lately I ve been trying to find a non carbon fiber from splitter for the R53.
Do any of you have any reccomendations?

Thanks!

 

M7 has one.
Check out their website.

 

 

You have a couple of options.

Both have spent a lot of time on the track.

 

I ordered the splitter from www.sneed4speed.com

I also just ordered the diffuser, canards, and spoiler extension from www.group4autosport.com

Can't wait to get them and try them out!

Ricky,

I can't find the canards on the group4 site. Do you have a pic? Thanks for the great info guys

 

We've got the Group4 splitter on our Wildebeest MINI: love it.

 

Could always make your own.. That's what I did and even sold a few to some friends. ABS plastic and or Lexan painted or covered in vinyl..

That flat green MINI looks cool.

come in different sizes plus you can get a matching wing extension

 

Second that, I like my Wyvern Mini Splitter. Good product, good price. Functional.

 

If you're using this on the track, make sure you have solid mounting points for the splitter, such as the crush tube; bolts in the fascia aren't good enough without some type of re-enforcement above 135 MPH. Ask me how I know....

 

How do you know? And what ripped off??

 

I had two turnbuckles through the lower grill, these were sandwiched between fairly large washers to try and spread the load.

It was then attached with four bolts to the fascia directly underneath the front lip; I sawed off the thing that hangs down vertically and attached the back of the splitter throw the two bolts that go to the rear of the skid plate--these are about the sturdiest places to attach to outside of the frame or crush tubes. It was a group 4 splitter (they are no longer in business, which is a bummer, they really are a great group of people).

Anyway, the splitter was set up at a slight angle downward (you want it about 1 to 3 degrees down, which in and of itself isn't easy unless you have a solid mounting point), and it definitely helped--when I crest the hill at Road America, I feel like I'm getting ready for takeoff, the car gets so light--with the splitter, the car sat down noticeably. And it was on top of that hill that it pulled out of the fascia with enough force to break one of the turnbuckles. I'll see if I can dig up pictures. I heard it go at 135 MPH, which is as fast as I'll go at Road America, and it did tear up the underpanel underneath the car, but no damage to the lower grill or anything you can actually see.

Sneed's splitter uses four turnbuckles, and that may actually hold up, but I just don't like the looks of it.

Dr. Mike did a really nice installation; google it on Grassroots, and that's how I'll do my next one--basically he took four turnbuckles from the bottom of the crush tube to the splitte;the splitter itself goes all the way back to the end of the skid plate (like I did mine, but without the solid anchoring). It's adjustable, and the turnbuckles are hidden. He can stand on it without it deflecting.

If you're putting on a splitter just for looks, it'd be fine on just the fascia. If you're hitting the track, IMHO you're better off with solid anchoring points. Some people get by fine without them (on the other hand, I've heard of people complaining about the splitter flexing significantly at high speeds when its attached just to the fascia), but my next splitter is going to go into something solid.

 

The Sneed splitter will hold up to 160+mph and I can stand on it (225lbs). Down force is 160lbs at 130mph. If the turnbuckles are not attached to the leading edge of the splitter you will have deflection in any splitter at speed. Thicker plastic (1/2" or so) helps to move deflection point up to about 100mph, which is good for the street.

 

Splitters should be down 1 to 5 degrees. The closer to flat the less drag you have but also less downforce.

 

I like the way your splitter comes all the way back to the end of the skid plate, I just don't like the four turnbuckle look, but that's just my personal preference, some people really like that look. Push comes to shove, if it'll hold that much downforce, I may have to go that route.

If you can stand on it, there you have for a functional splitter. Unfortunately the majority of splitters are cosmetic, but then again you (Sneed) are respected for making functional pieces.

Mike's splitter doesn't deflect because it can't--it's carbon fiber, not plastic, and it's solid as a rock (and light)--so no turnbuckles up front, and he can adjust the angle with the turnbuckles in the crush tube, which is pretty slick. It comes back to the end of the skid plates like yours, which is also nice. But it's a homemade project; I don't have the skill to make it, and to have someone else do it would be cost prohibitive.

Anyway, if you're looking for something that actually works and is durable, yours definitely should be on the list.

 

No worries man. I understand the stanchion look is not for everyone. I have seen pics of the one you're talking about i think and it was pretty cool and looked like it would work well too.

 

Oh, we are working on a no front stanchion street/track splitter but it'll have to pass bar before we can sell it. I'll keep you up to date. It'll be rated for speeds under 130mph but should work good for most street/track cars.

 

Sounds good!
