 I need to go on a diet!, my car weighs in at 2135 lbs. I think I can legally shed about 114 lbs. |

The car is all steel 914/6 with the excepton of lids and bumpers. It has a substantial cage. I just ordered a lightweight battery ...around 4lbs and will ditch the optima red top. Including the battery tray I estimate this will get me 34lbs. I also ordered a lightweight starter I think this gets me 10lbs.
That leaves me 70lbs. I've thought about fiberglass doors...maybe. Anyone have any other suggestions? |

That gives me an idea or two. ...most already done however.
I am now after searching the site considering a racing windshield.... I think that might be good for 10-15 lbs. |

What's the config of the car? My ITB-spec chassis comes in at 1874# empty of fuel, no driver. That's pretty much a stock body with rollcage and gutted doors, Panasport 15x7s and 205 Hoosier R7s.

All steel including flares, robust cage, reinforced chassis etc., gutted doors, headlights and motors removed, rear window is plastic, steering column stripped, dash stripped, aluminium case 2.5 twin plug with 915/wevo gearbox, 15x8/9 fuchs. enduro fuel cell... etc.  |

The aluminum case 6 and the 915 account for around 150 lbs compared to a 4 cyl car. Sounds like between what you're already doing and with mepstein's list, there are some good areas to drop some weight.

Sounds like between what you're already doing and with mepstein's list, there are some good areas to drop some weight. I would argue the motor is 150 alone the 915 even more on top of that (I rebuilt my race aluminum case into a mag race motor to save another 20lbs) to the OP: sounds like your giving up some weight with the heavy duty running gear do you run vented rotors on the back? heavy CV joints for the 915 (along with heavier stubs)? the flares and larger wheels are a challenge also... I'm about 1826#/ wet (no driver), right now with the same fiberglass panels as you and a 2.0/6 (similar motor weight/ maybe 20lbs difference for the mag case) read my build thread. there are more things you can do they take time, and some cost... but there are things the Jeff Beck 2.5/6 was rumored to be down to 1600 lbs (more fiberglass though) and also rumored to be 296 on the dyno imagine that power to weight ratio! is the 915 legal with CVAR? maybe FIA rules? brant |

I do run FIA. HSR allows the 915 box as well for a GT Spec car in gp3 and gp 5. That Jeff Beck... He can play guitar and drive like a mad man (IMG:style_emoticons/default/wink.gif) I have to run in the big bore group even if I have a 2.0 litre with CVAR. The flares alone take me out of c production. I could probably argue my way into b production with a 2.0 but doubtul it would be competitive unless it was a very short fuse motor. I'm hoping to take off around 100 lbs, I think the first 50 will be pretty easy. I believe minimum weight is 2020lbs. |

ooops…
frank beck apparently I'm a senior now I'm having senior moments does SVRA run you in group 6... ? (because of the flares) the weight things is a game of ounces. we took 500lbs out of our shell when we built it drilling holes, removing any non structural wire loom tabs, etc. I replaced any metal I could with aluminum... removed anything else I could to get the weight down.. it took a year... I don't run any engine tinwork, nor chassis shelf around the tin work... things like that are the long slow way to win the ounce war The SCCA screwed the 914/6 big time when the Datsun 240 came... vintage screwed the 914/6 even more when it let all of the Datsun put real brakes on the car and elimated their one weakness... CP was the right place for a 914/6 for only a handful of years, and by the mid 70's we were screwed... still I'd rather run in CP than with all of the big guys you have to run with now |

I've come to terms with it... Like I said, it's fun and on the tight tracks when I'm focused I can run at the back of the front runners. In the rain, I have a pretty good shot of winning overall which surprised me the first time it happened. I've yet to run with SVRA so I'm not sure where I would fit. I've only raced with CVAR so far. I'm thinking of racing at Barber with HSR in May though. |

JMZ, is it a real 914-6...if not and is a later GT Tribute. Replace the doors to the early doors. These do not have the heavy crash bar in the doors, saves 20 lbs. per door. The 72 does not have the bar but does have the newer window regulator. Mepstein love your list. Best, Mark
