Would have thought Shocks would affect turn in and exit. and that bars and springs affect more mid corner Graham?

I tested a Whiteline 24mm ARB just last weekend in me mk1. I was impressed.
And as for the weight, it serves a purpose. I would not change back to the thinner ARB. And almost every circuit car has too long front springs. Shorter = lighter. I halfed the lenght of mine when I went for stiffer ones with the new ARB. Still too long at 150mm

Re: A race bmw 316, now S14 powered again!

yes and no, its not as black and white as one does one thing and and another does another, shocks are there to control the speed the suspension moves at, mid corner and exit is more about ultimate grip, turn in much more about how the car transfers weight. on a slick shod race car actual suspension movement is very little so you have to make huge shock adjustments to have any real effect, ive tried numerous geometry, shock settings and spring rates, but never really done much with the front arb so i'd be daft not to explore that avenue

lol! been there before, buying shorter springs of the same rate just to save weight, not sure how cost effective it is thou!
and yes with the weight, if it makes the car faster then its the right move, the only downside is im not really going to be at the right circuit to judge the change, because i dont race much at snett and have never raced on the layout im on this weekend

Brake upgrade looks very neat, and definately a good move regardless of a little extra weight

Changing my front brake set up has made the biggest improvement on my car this year,luckily it also saved weight on my car....Are you going to be there this weekend DW?

Re: A race bmw 316, now S14 powered again!

Any of you lot tried alli wheel nuts yet? The price on them has gone down quite a bit so tempted but suspicious

EDIT:
I could start by shortening of the hugely too long studs though

in the uk your not allowed to use anything other than steel wheel nuts

Oh. Well no need to ponder that then. I still can though.

Re: A race bmw 316, now S14 powered again!

well i just changed the prop coupling, to do so centre prop mount needs dropped, that has steel spacers to space it away from the body, after all this weight gaining couldnt put the steel ones back so knocked up alloy replacements saved all of about 18 grams in weight lol!

Re: A race bmw 316, now S14 powered again!

Well hey everything counts!
Is the beemer close to minimum weight?

thats the spirit, every little helps, your'll be shaving your legs next and driving without socks on under your shoes

like the brake upgrade , i'm supprised the anti roll bars aren't bigger still for racing use though to be fair

Re: A race bmw 316, now S14 powered again!

race cars generally have very little suspension movement and stiff springs so roll bars are not that stiff by comparison, more used to fine tune,

road cars need comparatively stiff roll bars to control body roll, if car manufactures used stiff springs the ride quality would be unacceptable

nothing like it, im about 130kgs over it!, i could probably save 50kg with a careful build of a new car, going to split rims would save a bit. theres at least 15kg to come off me just need to cut down on the

The cars are weighted with the driver?
