The idea is to make this universal for other cars not just for GT4's so this will work for st202's as well. You just need to have a lip so the front is flat.



You mean the difference between GT4 blocks and Euro blocks on a 2 post wing?

no Difference between 2 Post Spoiler GT4 Riser Blocks vs TRD Spoiler. And if you have a roof spoiler throw that thing on your car also.

How about the wind drag at the front of the car with the stock gt-4 bumper and c-one lip.

I may have this done later in future as it cost us time and money to have a mock up model made and run a simulation over night.

Meanwhile back to this topic. We're in the process of making a prototype now.

Will having a 3" downpipe interfere with the fitment?

from the ST205? no. I have a 3" DP and it doesn't drop beyond the subframe.

What speeds are we talking about to get the benefit of these splitters?

^ Dang dude, you still post! It's only a handful of us OGs left. You're like one of the very first people I ever read on an automotive forum in my life. I was very naive back then, lol. Back on topic, any updates?

Awesome. I'll subscribe to this topic. I love your stuff.

Very critical . fluid mechanics will tell you that laminar flow is impossible at semi large speeds. laminar only happens at slow velocities. I don't know why everyone is obsessed about laminar flow because it won't happen anyway. What is of large concern however are the spinning vortexes of air at the back. These are called eddy currents and its the reason that tractor trailers and large trucks will buffet your car on the highway. Very high drag associated with those.
I would be down for any of these designs that reduce drag and increase DF. aka #2.

update!!?

hello?

im hoping for an update too.

I havent been in this forum for a while now. Mainly been working on my four and business closed till new years.
The mould is nearly finished and we'll be making a test sample and fiiting it to a track car in late Jan and I'll be able to post some results.

This looks really sweet. interest in seeing the finished product

yay.... one month later. where you at???

just a little bump so I dont have to search for it ha

currently being tweaked before making the final thing. I'm having trouble sourcing some turnbuckles suited for flat panels.
I saw that Nascar rear spoilers use them but I can't get hold of them in the UK.

Most hardware stores carry turnbuckles, I know there not "race car" ones but it doesn't really matter they do the same exact thing.

I can buy turnbuckles almost anywhere here however the ends are important. Ideally you'd want ends with a wide washer type surface so the force pulling is spread over a wider surface area on both ends or it'll just crack the panel and pop off.
Most hardware stores sells turnbuckels for adjusting tension on cables so the ends are usually ringlets.
This splitter tray creates ALOT of down force and so it needs to be bolted really well to the front end of the car. The rods will help it being dragged under and ripped off which is why I'm being quite specific about what types of turnbuckes needed.
