Turn it into a proper little track car

Plan is to strip and sell the interior, fit some compomotives, fit a roll cage with front and rear strut braces poly bush rear end and squeeze some more power. Aiming for 500bhp.

I want to fit internal ally fuel tank remove dash and have some kind of ally piece fabbed in for gauges etc, remove all door cards and carpets basically get it as light as possible!

Thinking about side exit exhaust but not sure about noise regs on track??

Anyone got any interior pics of a stripped and prepped saff??
