Reducing Front Weight Bias

[here2learn]

still failing to earn any credibility

i shall keep trying

[andy10v]

They are designed to increase caster angle (and are bodge job of doing that IMHO). )

What are the negatives of shifting the subframe forward that much? Wheel not centred in the arch?

[URquattroGus]

I am going to be honest and say that nearly all of the stuff discussed scares me!

If i was building a dedicated track car then yes, time to go to town. Having said that I would probably choose another car as a base in the first place.

As it is I want to keep the fast road car ethos, with the odd trackday. A lot of these changes involve compromises, and despite the fact this is not a daily driver, i like to have the ususability.

Very interesting discussion nonetheless!

So, a carbon bonnet might save 10KG? Does anyone make these/can they be made?

I saw a sport quattro one on the 2 Bennet website for 3000 usd. Seems a little pricey perhaps?

Radiator wise, is allumium actually any less dense than brass?

IMHO of course, I just don't like it as a mod, they are designed so that you have to cut the subframe strengthening rings to fit them (to stop rotation) and you will get contact with the arch liner on full lock, despite the fact it just looks wrong.
Can't image it does the CVs any favours running at constant misalignment either

In conjunction with offset top mounts, you'll reduce the wheel offset.

What about offset engine and tranny mounts? Could see 10-15mm offset of engine and box

Off topic.... But did you sort you loss of compression issue?

I would add the following to that list.

1) Manual cloth seats at front
2) Magnesium or light alloy rims
3) Monoblock Calipers and Ceramic Discs
4) Lightest tyres on the market in conjunction with Helium
5) Fibre Glass hood/fenders/bumper
6) Minus aircon
7) Titanium half shafts

There is much you can do to lighten up the Car. How far ya gonna go with it is the ponder

Yes, slightly embarrased but relieved to say it was only a spark plug!

When I broke down it sounded like it was not running on all 5, so is suspected a coil pack or wiring fault of some kind. Had a cursary look.

Couldn't figure it out and so decided to use my RAC member ship for the first time since getting it for my Le Mans trip about two years ago.

He comp tested all 5, with 4 being at 175 and he claimed the last one had no compression at all! So I took his word for it and did not want to run the engine in case of causing further damage, presumed the worst and sent it to Pete Berry who built the engine and it was a f"cking plug. I think I may need to run slightly colder plugs.

I have filed a complaint to see if i can get anything out of the RAC.

Incredible.... But a cheap fix....

Yes, I had a mate wth me and he helpfully posted this photo on Facebook:



We had just popped along to a local classic car show, and i might have just slightly taken the piss out of the Metro

Also had to watch as scores of 70 or so year old cars sailed past, whilst i was sat there in a layby with the bonnet up

[Colesy]

Surprised no one else has suggested this, but I was thinking...


Wouldn't adding something heavy to the rear have the same effect?




















Like this:



or maybe not so heavy:

What's the problem with CV's runing at constant let's say 15 degree angle? GKN states that their AC and UF joints handle approx. 50 degrees, so we have up to ~30 degrees for tuning and wheel travel. If it's not daily drive car you don't need to worry that you won't be able to drive like 250kkm with such setup

Good info thanks
What about OEM joints?

[nervas]

I'm waiting info from GKN Motorsport department..

by the way look at GKN OEM CV:
