Hi Bart, I have a friend with a Gen 2 rally car as well. He dropped from about 980 to 925 by changing to lexan side and door glasses, gutting his doors and running fiberglassed fenders, bonnet and bumper. Not to mention I have realised that all the stock mounting points for bolts (on the floor and the pillars) are actually thicker metal with nuts wilded behind them. I am sure there is a significant amount of weight to be lost there. I think my extra ten kgs could be lost with those heavy side impact door bars, the bonnet ribs and gutting the trunk. I have a 98 RS shell to build for next year, so that car will be built as light as possible so I can add weight where it matters, down bottom

I've not got any composite parts yet, bumpers and bonnet would make a big difference.

Is your air box totally sealed or is it more of a heat shield around the pod filter?

If it is sealed, is there things to consider when building one?

Its fully enclosed, but has a 1" hole underneath to prevent it presurising, also lets out any water. When I was using the stock ECU it used to misfire when there was positive pressure at high speed, drilling the hole totally fixed the problem.

Thanks, I was wondering alright how you would work out getting the pressure ok.

Finally finished the sump guard and just trial fitted it. Its a composite construction of Aluminium and Kevlar and only weighs about 3.5kg, less than 1/2 what a 5mm alloy plate one would weight with the same dimensions.

Also now lined the tunnel of the car with heat reflecting alloy tape, hopefully it will get the cabin temps down a bit, but suspect the black roof is just as bad if not worse.

bart you might want to look at folding the front lip upwards a bit - just thinking that when your cutting the corner as per:

You might run the risk of catching the front on the road. if it's bent upwards it will act more like a ramp.

Not sure if you can make it out but on my car but you can see a wire hanging down in front of the sump and a black tab on either side of the wire. Thats where my sump guard mounts up to.

So should you do this:

You don't crack your sump.

It will actually sit above that bottom part of the lip, not on top like it is my picture. It was just a trial fitting to make sure it wasn't going to touch the exhaust.

Thats all good then...

Just was thinking it was screaming out... i'm going to tear myself off! and watch what i take with me!

Also, the lower part my bumper is reinforced with urethane foam, the factory bumper/lip combo is hopeless, it just flaps around. Mine is solid/sturdy, yet should be slightly forgiving should it receive a hard impact since the foam should crush up to a certain extent.

My Sump guard doubles as a lower strutbrace now too. Initially I thought I'd bolt it to the lower brace, but ground clearance is low enough as it is without losing another 5mm or so.

looks good bart love the car!

Its funny, the sump guard annoys me simply because its weights more than what was there before which was of course nothing.

So in the never ending quest to save weight, I replaced the factory bonnet stay with an alloy one. Original was ~380gms, the replacement 75gms :wink:

Its the little things that matter :lol:

Just finished replacing the stock rear brake rotors with new slotted ones. Replaced because they had reached the wear limit.

I love slotted rotors you can get great feel from them

For more like that and you get a Kg. You could do a gen2 style side mount one thats half the length again.
