Here is a question! What does the twin pane sunroof add to the weight of a 07+ Mini?? Top heavy weight is my thought, but how much?? Stephen
I think I remember reading somewhere it's about 70lbs.....seems like a lot to me if that's true, but between the glass, motors and mechanisms that could be right. I bought my new Clubby without the sunroof, but mostly because I don't like paying for something I never used. That and the heat gain.....I do wish the rear windows either on the sides or the barn doors opened tho, so I could get better flo thru without the buffeting that comes from opening the fronts.
Just did a Customers 04 Sunroof car, Back seat removed, light weight wheels, Amps but no sub or box yet, Invidia exhaust, 2770lbs... WOW! ( I didn't make note how much gas was in it though) On mine I found the stock seats were 51lbs each. Put a 8lbs kirkley aluminum seat in the driver seat and the passanger seat takes about 10 mins to remove or put back in and saved nearly 100lbs right there. I think I lost 45lbs in the wheels, 8lbs in the shocks, 15 lbs in the clutch flywheel assembly, 22lbs in the battery and the rest came out of the header/exhaust.
Since the gas gauge is so crappy a full tank is the only way to measure the weight. For those that don't know where to get their vehicle weighed and cannot drive up on a roadside truck scale, like you can in Oregon when the scales are closed, because they leave the metering lights running, then go to a gravel company. They weigh their trucks when they leave the yards and every one I have been to has said "Sure, no problem, but if you want a registered weight it will cost $$(5 is usual)". I have been shocked at times weighing my vehicles, some real low weights and some, like a U-Haul, was 50lb below the 24,000 gross weight! 70lb sounds about right for what the foosball table twin sunroof, thanks Dave! I whited out the sunroof because I too hated the heat gain and I must admit that I do use it to vent unnecessary heat but never do more than tilt them up. The possibility of water leaks is always on my mind. Opening side windows, like pop out vents, would be awesome! A buddy has that on his Landrover(powered ones) and they work great! No wind noise when the front windows are open. Stephen
Unless you are regulation drag racing with a qualifying and inspected car reducing a cars weight to much is not always the best idea. There is a point on production cars lowering the weight starts to compromise the structural integrity and safety of designed parts. You mention cage (not roll bar) that would indicate class regulation race car in which case the challenge would represent a race car and not a fully legal and functional street car. In other words a street car in the real seance and not a race car with a register license plate.:lol: There are down falls to having a car to light as well as to heavy!
I'm working on it! I review your build thread regularly to make sure I'm not forgetting something. The rules under which I'm building (BMWCCA Mod) allow me much more freedom in the use of composites than your rules. I should be quite a bit lighter. 2000 lbs is the goal. I think that Onasled came in at 2050 lbs.
Took my 2009 Clubman S to the track yesterday, 2885 with no sunroof, full tank of gas, auto trans, 17" S lites and me out of the car. My buddy's 2002 Justa was 2765, sunroof, almost full tank, CVT etc.
Good luck, there is a crap load of stuff removed from my car and it still weights 2600 with the pass seat in, it's that silly roll cage thing that is killing my weight.
I need to officially weigh my car, but I'm pretty sure I might have the lightest Countryman All4. Roughly around 3140 lbs... Lol. Heavy compared to fwd.
