I need some history - what's up with these rules?

haha… i don’t think you need “that” much ballast :slight_smile:

Dang - this thread kinda got off track…

Can someone post a photo that shows what an “aftermarket” nose/spoiler looks like on an 89-91 car?

thanks

Hey thanks guys,

So any of these would be Spec E30 legal - or just the ones that “resemble” a stock front bumper & chin spoiler?

Some of them look pretty racy with a REALLY LOW tolerance for curbs or any agricultural off-track adventures…

Fiberglass spoilers and off-track excursions are an incompatible combination.

My reading of the rule (9.3.13.3.1) has one requirement - maintaining the original crash bar. So your bumper choices are limited only by budget and imagination.

The spoiler/splitter rule still has its measurement taken from the front bumper (max 2" forward), effectively neutering the splitter rule if there is no maximum dimension for the bumper. I had suggested a splitter measurement from the front hub to ensure all cars were using the same maximum splitter length, but that didn’t make it into the 2010 rules.

Which means you could maintain the original crash bar behind a 1970 Plymouth Superbird nose cone bumper assembly, then add a foot-long splitter that would smooth airflow under the car ('cuz it would only extend 2" beyond the ‘bumper’ ). That’s the hot setup for Lowes. :wink:

Now it is Gasman’s turn to argue the intent of the rule. :laugh:

PS - I agree with others’ comments about splitters and spoilers. I donated one to the gravel outside the carrousel at CMP. At other tracks (Miller), running a splitter is definitely worth the risk.

One word… Junkyard

The light backing plates fly off on track - you guys aren’t BMW Club members? Happens a lot in contact situations

I am pretty sure, it’s been a long time, but you can retrofit a 91 front end spoiler on an 87 - correct me if I am off base.

Junkyards are probably full of them… They are durable and can be fixed.
