Half doors

[peter030371]

Winter update. I have now fitted half doors to both sides and a standard RAW vinyl boot cover.

Taxed the car over the weekend and waited for the roads to dry. Eventually, yesterday afternoon, I managed to get out in her for 10-15 minutes on my normal 'test' route and up to circa 80mph the reduction in buffeting is very noticeable in the cockpit. Very pleased with the results

Now need to do something about fitting a rear 'diffuser' to reduce rear drag (not in any attempt to pretend it will generate downforce!) and the car is getting better with each mod

Diffuser will help with the parachute effect that normal kit car bodies produce.

I no, I had got a GPR diffuser to fit but by the time I trim the width down (10mm each side) it will take the outer strakes off and will look a bit daft with inner strakes and no outter strakes (the inners are moulded in so can't be removed). More to the point it will lose its strength without the outter strakes. Think I will have to sell this GPR one on and after lots of measurements and cardboard models I think I can make one from Carbon NV fit with some cutting about

I'm pretty sure I bought a standard Westfield one which fitted. It was a Plays Kool one.

The one I am looking at is a Westfield (narrow) one from Carbon NV. The width looks spot on but the length will need 'adjusting' with a jig saw to fit

Me being a weight watcher I can get a GRP one like you suggest for about £100 which weighs circa 3.5Kg or a Carbon NV one for just over £200 but weighs less than 1.5Kg. Guess which one I will be going for

I haven't got time to fit it just yet so that will be later in the year now.

Are you sure about those figures? The standard weight saving/cost diminishing return chart (and carbon is usually well down the chart) says that double the cost can't get you more than 50% weight saving.
