What to do next?

I have a quandary. Having now got the suspension under something like control from the point of it no longer arbitrarily choosing to ricochet about like a rubber ball, I am now giving consideration to reducing the actual movement under dynamic loading. There's a couple of ways of doing this. First and most obvious to the uninitiated is to fit huge wheels and low profile tyres. This is not cheap with the rims and tyres coming in at significantly more than 250 pounds a corner. The benefit of this is it will look cool, improve turn in feel and braking stability. The disadvantages, it's abundantly clear that the car has been played with, the nvh transfer of low profile tyres is significant and it doesn't stop the body moving under weight transfer. The second option is harder springs. These are less than a fifth of the price for a set, and are totally stealthy. The advantage is less body movement which will have a benefit in turn in but nothing like the low profile tyres, flatter cornering, more efficient weight transfer for braking. Disadvantages there is a limit on how much ride quality having the majority of the compliance in just the tyre sidewall will give, the springs in question are not a direct fit and will need to modified to gain the correct ride height further stiffening them, having stiff suspension and relatively tall tyre sidewall profiles can induce uncontrollable bouncing under braking like a tractor.

Yes I know that the answer is to buy a 911 turbo and just drive it but I can't. Built not bought.

I used to be indecisive but now I'm not sure.

I keep an eye open for a diesel sway bar but the last one i found would have been nearly 160 pounds with shipping from France!

I like the idea of the adjustable drop links as by their construction they will have little or no flex in the stem unlike the factory ones. Tyre wise I am kinda set on 18s but only cos I can't find any 19s that are a direct fit. The other reason for the harder springs is not to carry more weight but to carry the current weight better while still maintaining standard height. But I don't want it to be like my old 90 that only rode properly with half a tonne in the back.
