Front Splitter

[Jhonno]

Yeeeeeeaaaah boi.. I can cut my home to work lap time by 2.2sec with my new front splitter innit. It tames the front end of my 540i M3 barn find on the roundabouts innit. Proper glues it to the road.

I'd keep the swift, if it's a 3 cylinder model you can pretend you are in a 911 if you shut your eyes and take your hands off the wheel whilst at full throttle

i put a sport evo splitter on my m3, it's a full width flat splitter with undertray which extends a foot or so behind the bumper too. even on the most extended setting you'd struggle to tell any difference at all at less than 100mph, and that's on a car with quite a lot more aero tweeks than a normal e30!

go for splitters if you like the look, but don't kid yourself that theyll make any noticable difference in normal driving.

yes, stopping as much air as possible from going under the car is a good thing, but to actually work the splitter needs to be as close to the road as possible, and you want skirts as close to the road as possible too otherwise all the air you've stopped going under the front will just rush in the sides.

then you'll want a rear diffuser, and something to stop turbulence over the top edge of the rear screen. if an m3 rear window is too rich, maybe an e9 csl style roof wing to direct the air over a tail spoiler....

If you want to change the handling characteristics of your car through aerodynamics, as everyone else stated, you're being a bit silly.

If you're trying to force more air over the top of the car to improve downforce, there is only one option that might actually provide a noticeable difference.

You could fit stiff brushes around the entire car, touching the ground. Then a tangibly larger amount of air might travel over the car. But it might also travel around the car!

As someone earlier mentioned, the e30 is an aerodynamic brick. A beautiful brick... but nonetheless a brick. There is no smooth path for the air to be forced into over the car. The front grill pretty much ruins the chances of that.

I am planning on a turbo conversion and track days so a working splitter of some kind will help, since its a relatively cheap modification i was was simply asking if there are any available for the E30 and if anyone had used one.

Yes its only a 1766 M10 Inj but with a turbo conversion i could be potentially looking at over 300BHP (318i M10 making 320-350bhp) so on track an effective front splitter would be a useful and probably worthwhile addition, along with 51mm struts, coilovers, rear discs and generally upgraded brakes, however this is further down the line, maybe 18-24mths down the line, trying to find out things in advance.

No the swift is not a 3cyl is the 1.3 4cyl SOHC, also looked for a turbo conversion for that but they are only available for the G13B not the G13BA like mine so i can't use that for some track fun, a G13B engine with a turbo kit and all relevant extras can give you upto about 250bhp on a swift but it would probably work out most costly than a turbo conversion on the E30. G13B Lump is about £800+ carriage (fully rebuilt and uprated crate motor), then another £1800-£2500 for the turbo conversion plus labour, thinking the E30 will work out quite a bit cheaper and more worthwhile.

And before anyone wants to continue taking the piss, i have actually priced up the swift turbo conversion for my old swift about 2 years ago, plus we all know E30 turbo conversion have and are being done with good effects, anything you can do to help with higher levels of grip while on a track will make a difference, even if you can't actually feel it (ie a front Spliiter), and remember a front Splitter and front spoiler are two very different things. Splitters have an actual purpose to split the air either under or over the car and they extend forwards past the bumper where are front spoilers are basically an air dam and are designed to look good and not much else. Yes a splitter cuts acceleration and top speed but thats not really and issue in an E30 as they are not quick by any standards (apart from modified ones).

You should've bought your mate's 540i.

[Kos]

here's the splitter you need

This just gets better and better!

You're clearly not wired up right - but keep the stories coming!

[Duke137]

Steviebmw is selling a big front spoiler/splitter that may be of use to your E30?

(If not he could probably make it fit your Swift as well if you change your mind.)

[staley_turbo]

Bodging a splitter on and getting 350 horses out of an m10 are two very different things!
Id stick to the splitter.

[Semperboy]

does the volvo splitter fit straight on or would i need to make some adjustments?

[Rav335uk]

Needs to be mounted upside down onto the valence.

[Alex]

IS lip FTW

I'am sorry but the volvo one looks utter utter shite

cheers mate

[hongkongfuey]

i think the is ones look shite, and for the money, volvo ones every time

I think you need to get in touch with red bull, as it sounds like they need your aerodynamic expertise!

Your knowledge appears to be the sum of a vivid imagination and snippets of facts you've either picked up in conversation or internet research

Real world experience is something rather different, especially in the world that revolves around fine tuning aerodynamics and the effects of

I'd recommend you install an mtec2 kit and discuss the extra weight you carry vs the overall benefit of reduced drag - in all cases the effect of any spoiler, splitter, wing, foil, whatever, is just there to reduce lift & if anything aide overall stability.

How does a splitter cut acceleration on an e30 exactly?
