Ways of reducing the weight of our cars
s3dubbin:
Do you think you could remove too much wgt? Make the car too light that traction off the line is effected? Possible?
the bruce:
Fuscobal, unfortunately I have not.
But I'm very interested to see how it works. :wink:
S3dubbin, NO. :signLOL:
Of course there are some places where it helps more and some where it helps less.
Save weight on front and way up (roof, windows) and more on the driver's side (UK)
than on passenger side. The engine is much heavier than the gear box.
Carrera2RS:
The front rear weight balance is very poor, I would not bother reducing any weight at the back of the car. My Pirelli came in at 918kg over the front axle, 526kg over the rear. This is with 1/2 a tank of Petrol, TD pro race alloys and TT arms. If the front mounting bar weighs a lot this could be interesting, frankly VW should have tried harder to mount the engine further back in the chassis. Coming from an E92 M3 you do understand the difference when the manufacture tries harder with basics before they look at the right bits.
I will enjoy my Pirelli and will continue to tweak, knowing it's a GTi. So far Stage 2, PSS9, TT lower arms, Neuspeed arb's, WALK, 8x18's, awaiting VWR brakes or AP Racing, Forge twintercooler (to keep the modest stage 2 on the money in all weather) for me the power is more than adequate for the shell. I thoroughly enjoy the chassis and car in the knowledge it comes from a more humble starting point, expect too much and there will be disappointment !
I keep looking at the BMW 1M....... :smiley: at £40k it really ain't bad when you look at the build and bits.... 9 and 10" 19's with good tyres, M3 brakes, M3 light alloy suspension, 3.0 L twin turbo, superb diff, close ratio box, etc
fuscobal:
What I can do on front besides the reinforcement bar is the battery. I now have the Power Cell 3000 wich weighs an impressive 27Kg > http://www.carhifishop.at/Power-Cell-3000-Batterie . I have recently found a battery that can take care decently of my audio system and weighs only 12.5Kg > Odyssey ER40 > http://www.odysseybatteries.com/batteries.htm
Problem is, my Powercell has like 95Ah and the Odyssey only 45Ah. I hope it will meet my demand as I'm not listening to my music at loud volumes or with the engine shut down !
Hurdy:
This is the issue with the lightweight batteries, but if you take care not to run electronic systems in the car with the engine off for too long you should be fine. It is the crank amps you need to ensure match up. Try the Braille batteries. I'm sure someone on here has a 9.5kg one fitted with no side effects. Crank amps are impressive too at over 1300

Or if you want it to look sexier, you can have it with added carbon fibre :drool:
