You also need to give serious consideration to just how good you want the upgrades to be. Just upgrading to high performance discs and pads could easily set you back a grand and you will want one of the Corbeau or Cobra pro range seats if you're spending a lot of time in there. The cheapo stuff honestly isn't very good. No reason not to buy a used seat on ebay etc. but unless you get lucky that's likely £200 - £250 each. Sliding rails to fit said seats will be extra, probably £150 each again.

To be honest, unlike many, I'm not in this to create something that is pretending to be a racecar. I trackday because I enjoy driving, not because I want to squeeze every last ounce of performance out of the car - that's for racers. I'm not trying to build a car that will spawn a 30pg thread of cooing in Readers' Cars - I just want something I can enjoy driving.
Spending a grand on coilovers probably won't give me significantly more pleasure than a budget set. Likewise, with FIA-approved bucket seats available from £250 and sidemounts from £50, there's no reason to splash out megabucks for a brandname.

You can have great fun for £500 i agree, but hey....

I spent less than this to buy half a trackday car and get along to several days in 2016. And I laughed my ass off the entire time. Trackdays are the best example of diminishing returns I can possible think of, in entertainment terms.
