Get a shorter ratio diff...job done and will not interfere with reliability etc
plus you'll have about £400 left for 2 track days and some fuel....

was hoping for some ideas has no one done any performance mods?

Richard, you won't find much more of a modified Z than Jason's. The mod he suggested is mentioned quite a lot on this forum and utilised by quite a few people. You could always look at a lightweight flywheel which will improve acceleration as well.

Repeat.....shorter ratio diff.........echo in hear!?

And as Justin rightly points out a light flywheel will also be good but will mostly likely take you over budget. Try a good remap by evolveyourcar.com

If you're looking for serious poke a supercharger is probably the best option

If budget isn't an issue sell the 3.0 slush box and buy a Manual M then you won't need the aftermarket quad setup either!

You could also try to lighten your unsprung weight by fitting some light weight wheels. You can save up to 4 or 5 kg per corner.

The general rule of thumb about unsprung weight is that it is worth about 6 x its weight in performance benefits so a saving of 4 kg / corner adds up to about 80 kg equivalent saving or like removing one average adult from the car. You would get better mileage too.

Ditto - I like the end pieces!

Any chance of taking a pic underneath the car to see the backbox/pipe layout??

This is the battery in the position they left it for me, do they not know space is a premium, going to body shop in the morning to have it put in a propper place middle of boot under tool tray, will take pic of boxes underneath the car when i get my baby back on friday

Where do we get lightweight wheels- will the steel Z3 wheels fit and if so can bigger tyres be squeezed on?
