Development of our MK4 Rs for hps

25-30kg for a front seat if I read Vortex correctly and the whole rear seat assembly is around 50kg or something stupid like that.

lose as much weight as possible would be the name of the game!

It's cheaper too..

Comes back to the fact that there are heaps lighter cars around for tracking so a dedicated track car would be the way to go instead of ruining your daily driver by ripping everything out, and having no comfort. Just my 2c..

if it were a weekend driver yeh then it would be justifable, however if it was an everdayer then you'd hate to drive it in stop start traffic.it would have no bottom end unless you use shorter duration cams it would be pointless,

Iam hearing this alot about cams losing bottom end...but my assumption is if you do cams must do porting otherwise deffently a waste of time...

The stock exhaust is a heavy pig of a thing, if I remember correctly the B&B replacement exhaust we installed was around 50KG lighter than the stock one. The Oz Superleggera wheels are 10KG a wheel lighter than the stock Aristos, Rear seats weigh an absolute packet as they have a metal plate in them to protect against rear impact, the front ones also weigh a ton, stereo and speakers have all been removed, airbags are disconnected but will be removed when we go to club rego and full weld in cage, the list goes on. Once we go to full weld in next is to remove the headliner and whats left of the carpet and dry ice out all the sound deading. Over all so far we have reduced the weight by over 100KG and that is with installing a full bolt in cage, I'm pretty sure we can lose at least another 50 with all the headlining carpet, airbags and sound insulation add to that a battery relocation and replacement with a light one. As mentioned reducing weight is the easiest and best way to pick up free horsepower.

Very true Al...cheapest way too

You're in the Mk 4 forum remember.

It's not all about the latest, greatest or fastest stock car you know.

I think the greatest bit is quite applicable.

I know what you mean, but it's also good to keep your feet (and wallet) on the ground and everyone knows it's much cheaper and easier to mod a factory-turbo car than any kind of NA mods or conversions..

Also you dont have to get the latest and best, any S3 in good condition would be awesome..

I'm faced with the same thing so not winding anyone up, just have to enjoy it for what it is with some light mods, or buy something faster.. my 2c.

Can you get dyno graphs before and after? It's the only way you'll really know how much of a gain you got...

It was just a realistic alternative before throwing heaps at it, but am all for improvements if it doesn't detract from the car.
