1. The car can be driven from street to track and track to street without modification. It can be both streetable and trackable. 2. The car can be legally driven on the street, and the comfort is at least the same as stock. 3. If BMW engineer's do not have to stick to a budget, and can sell the car at whatever price they want, what would they put on the car. 4. Majority spent on the mods will be form follows function. For example, the grilles, and gills cost a lot less than my wheels. That's also the reason why I question the logic behind a GruppeM CAI over aFe. Is the $1600 extra going to be for function or is it for bling? For clarification, I said that I am unsure of catless dps because it is against my mod philosophy.

Everything I have come across in my research says there is issues with running aftermarket cf hoods. I doubt you can rely on saying a GT3 RS has a cf hood if you get pulled over. Not my rules, just stating what I know already. You can have a custom fibreglass hood made that complies with ADR but it will cost $$$ and there will be some down time.
If unsure, call Dept of Transport. Also you've mentioned a few times you want to keep your car street legal but uncertain about catless dp's which are illegal. Doubt anyone would ever pick up on it but having a CF bonnet is illegal and very noticeable. At least dp's are discreet. Not saying you shouldn't do any of these mods, but they are clearly illegal when your philosophy is about being street legal. My philosophy is building a decent street/track car. One that I can drive every day of the week and take to track. Only things I ever need to change are wheels/tyres and drop the oil/filter and brake fluid after each event. |

![]() These safety requirements means that you cannot just scan a bonnet, modify it in a CAD, mill the mould out and just lay any CF and cure it. The whole component including attachments needs to be redesigned because CF has different properties to steel or aluminium. This means a lot more cost involve than the Revozport, or a Seibon, or a Vis which are really cosmetic based product. There are certainly legal (and safety!) issues with aftermarket CF hoods, but it is not a blanket rule and there is no rule in the legislation against a hood made of any specific material. The hood, needs to comply to the safety standard in the ADRs for both occupants and pedestrians. My target is GT3 times - not sure if I will get there, but that's the aim.

I believe in RTA all you need is an engineering report that the hood is made of a good standard (in engineering terms). The specific requirement is that things can't be caught in the vents if there is any.

Okay, just thought I'd mention it incase you didn't know as you want to head down the legal path, but you already seem to have it covered
![]() If it were me I'd go with what's already available, you're only illegal if you get caught ![]() Btw, the Revosport 1M that was at the last club run needs to jump on here and post some photos. His car looked fantastic. I'm sure you'll have one of the best 1M's going around when you're finished with it Steve. |

There is a thread comparing the PSS and some Pirellis the 295s are as wide as the 305s. So I think it is the combination of both which is the issue. Only time it rubs for me is when I pull in or out of my driveway.

So weight savings are about 3kg per wheel?
This is a great thread for those seeking wheel info for M3/1M http://www.m3post.com/forums/showthread.php?t=265756 |

That's BBS FI. Sparoz's is RI-D, which are essentially lightweight FI.
They are made of a special military aircraft grade alloy and forged through a rather unique process. Hence the price/weight/strength. |

![]() The Advans @ ~8kg seem the lightest... so saving 4kg per wheel. Don't look as good as Sparoz's wheels though. |

Going by the caption - the wheel above is from the GT2 hence the centre locking hub. |

That is just a brilliant saving. I will probably get a set when it comes time to change my tyres.
