I guess I'm biased but Christ, lifes too short for all that! Especially when the cars were set up pretty well to start with, especially for the road.

A 15 year old car with loads of previous owners is more than likely to have had suspension components fiddled with/changed/replaced over the years, any one of which could easily have affected things? Even if the components haven't changed, geometry can change/fail due to kerbing, potholes, metal fatigue, bush wear, incremental joint play etc etc - much of which could have occurred before you even owned the thing.

 

If you haven't checked the HCBs and ball joints on the tie bars then it might be your life that could be cut short!

 

I've had a HCB failure on the rear of my car due to a pothole which also bent a rear wheel. Luckily I noticed immediately and limped the car home carefully, however it could have been far far worse if I had not noticed and been belting along.

Trying to borrow some corner weight scales at the minute so I can do that and then redo the front and rear toe.

 

Having weight in the car will also effect the geo so it's worth adding ballast acording to how you normally drive it.

I take the passenger seat out and put 70kg in the drivers seat (although I put a little bit of that in the footwell as not all my 70kg will be going through my arse (more for the corner weight though))

 

You could also hang a pole across the front and rear and then measure from the centre of the pole to the edge to hang the string (I use fishing wire)

70kg...you have a heavy Christmas?!

[Zoobeef]

I'm actually at 75kg after Christmas. 70-71kg is my normal weight.

That makes me feel better...not, if I knew what kgs were I'd probably be over 100. I do & I am but at 7'2" I could get away with it.

You're 7'2" and fit in a VX?

I don't have a 'problem' with Geo in general and the reason I say I may be biased is because I've always had high-end equipment (excluding corner weighting gear) at my free disposal but going to the effort of sourcing and storing 5 meter straight lengths, tape measures, string, checking levels of garage floors etc etc. too much for me personally.

 

It's fine if you like tinkering, and I know you do, but for most, it'd be far easier to make friends with somebody that's got the kit, they don't even have to understand the mechanics of it nowadays with the better kit, greens good and red is bad. Get it set up once, put a datum line on the tie bar and if you want to tinker, work in half and full turns.

Yep, I can understand not being arsed, as it is time consuming. But, I would imagine that many cars could gain an improvement in handling if they were checked and adjusted.  

[hairy]

I'm actually at 75kg after Christmas.

 

You're not trying!!

[Aerodynamic]

Im far from convinced here. First unsprung weight should be as low as possible, but its also relative the cars total weight. You say your handling improved by adding bigger brakes. By 4 kilos on each side. But the speedster is maybe a bit to rear biased. What if you just added 10kg in the front but not on the wheels. Than maybe or probably your handling would improving even more. Porsche is not the perfect car, it also need a to sell by design. Look at F1 car, they have very low unsprung weight and they are quite fast, about the fastest thing on this planet. Br, Per

Actually makes sense a lot of that Never. I'm not convinced on the unsprung weight but having reset many many "premium" geoscience over the years it is frustrating at times to see the frankly awful results people get having pain in some cases 100s of £ for someone to make their car drive awfully. Of course the geo is the ultimate placebo mod and you could probably get good feedback from doing nothing. Most of the really bad geoscience are people buggering about with caster and toe settings making them feel darty but normally at the cost of stability.
