I'm not saying we're not interested, I'm trying to be helpful?

Corner weighting is a great deal different from setting up adjustable suspension, which of course is absolutely essential.

Corner weighting is the process where you try to get the car balanced in terms of equal weight distribution on the wheels. This is of course impossible as the engines in the front so you will always have more weight on the front axle, thats natural but what you're trying to achieve is a 50:50 displacement of weight from corner to corner (ie front left to rear right and rear left to front right).

You do this via small changes in the cars ride height on the suspension, sounds simple enough but once you change one corner you change all the other 3 as well, by different proportions so its a time consuming exercise of adjusting each corner then going back over again until its right. The E46 is very easy to get 50:50 (its normally shown in percentage terms, 50%) as the chassis is so balanced anyway but a proper corner weighted set up is worth decent time on track.

However (and this is where I'm trying to save people money) the process is very specific, the driver, wearing the exact clothes he wears on track, complete with helmet needs to be in the car for the entire process (when we dont have the driver we fill the seat with sacks of spuds, weight etc to match the drivers weight), so plan for a few hours sitting there reading a book. On a race car we know exactly what weight of fuel we run, each litre is 1kg approx so we corner weight the car for race fuel weight, we re-corner weight for success ballast (60kg win penalty in CSL Cup) as these make dramatic differences to corner weighting.

Apply this to a road car, add a tank of fuel and you've got 60kg added, if you've corner weighted it with half a tank you're now 30kg out and you've wasted your time. Run with a passenger? Again, waste of time, 80kg sat next to you will throw it out massively.

My point is that corner weighting is a racing thing or at absolute best a track day car where you are trying to get the last nth degree out of a laptime, for a road car its a nice way to spend a couple of hundred quid and make you feel better, if you have the money and want to be quicker buy a set of new tyres, or instruction make use of it rather than spending it on something that you dont need or can make any real use of.

I'll happily do it, charge you the labour anything you want, but I'd rather educate people on what to spend their money on rather than just take it, sorry.
