Subbed, would this interfere with a beatrush under tray, i have one coming in from Japan. Would def be interested in a rear diffuser also.

That is possible and Dallas has been pushing me to start getting into composites but the 3D carbon/aramid stuff starts around $2500 usually. I don't think there's that many people trying to drop that kinda money on something that's going to end up eating a curb or dirt.

This would replace the undertray so the beatrush would not be needed.

Ya doing a "run" of them doesn't make sense, but taking a custom order just like you'd do for these could suffice. All the other startups came from a guy getting into composites for his class of car and his friends, and they don't have time to build for anything else, so it may as well be one of us lol.

I would definitely be interested once you get everything is sorted out

Looking at prices of raw composite materials its a super steep climb to carbon fiber, but kevlar is pretty stout and cheap. There might be some environmental reasons to not use Kevlar but if its protected with resin and from scraping it might be good. Though its hard to be at alumalite.

And it's not just the material cost, it's a TON of labor time. You have to make a mold out of fiberglass, then lay the carbon/kevlar, then cure it, then post process it, trim and blend edges etc. Not to mention the vacuum you'd need to get a good seal on something as large as a splitter is pretty pricey, and there's a fair amount of consumables like peel ply and vacuum bags plus all the resin and fiber.

If/when I get into the composite stuff I won't be starting with splitters.

For sure, carbon is for the ultra high end or posers on the splitter.

Thats really pretty,

Can you show some more photos of how its mounted? we learnt the hard way about mounting splitters after having one tear off at speed. I see you mention its mounted to the chassis but interested to see how youve done it.

Also how is the flex on that alumalite? can you stand on it and it not flex at all? be surprised how much force air makes on a splitter at 200kmh haha. The human bodyweight test is generally the accepted method of testing a splitters strength haha

Theres no real benefit to using carbon. you could get a nice high density composite honeycomb or "foam" and then cover it in fibreglass and it would be stronger than alumalite and lighter.

I think you've posted how yours was mounted before right? I assume now its quite a beefy mount after losing one.

Yep i did in the aerodynamics thread a while back.

Its just 4 rods with rod ends that are mounted to the chassis rails on one end and pinned onto the splitter on the other end. 2 at the front 2 at the back. but then its also screwed to the bumper where as this isnt which is where my concern is.

Okay guys so here's the breakdown for the splitter stuff: https://docs.google.com/document/d/1...eGPKw6AkQ/edit

I should have the mounting brackets sometime next week and as long as they fit properly things should get finalized pretty quickly.

That is an impressive amount of work! I'm watching closely and may pull the trigger on this in the near future. What about the stock crash beam may prevent mounting the supports btw? Have you considered dibond (ex: 6mm thick) as an option? alumalite tends to end up quite thick and u have to figure out an edging solution.

Can you not also just buy the voltex endplate and mount it? http://www.inspire-usa.com/Voltex-Si...r_p_2521.html#

Man i want the half but as previously stated i have a bearish incoming, wondering if there is a way to modify this or the beatrush.....

Thanks!

I don't think the stock crash beam will be an issue, I just haven't had my hands on one to confirm. Really, all you should need to do is put a couple holes in the bottom of it and put some bolts through it.

The alumalite is 10mm so yes it is pretty thick. I can get 6mm alumalite too but I've had 6mm splitters before and they crumple VERY easily, the 10mm can take a lot more abuse. I have an edging solution so not worried about that 🙂

There's no reason the voltex end plates wouldn't work but at over $250 that really hurts haha. Mine will cost less than half that and I can make them any shape desired.

As long as the beatrush was modified where the mounting brackets come down off the core support there's a good chance they could be run together. But it's kind of a double redundancy to run both.
