Now I am keeping my Sporting mk2, I am having a small crisis on whether I should update change it to keep the interest high for me personally.

My options for time being now are to try and make my sporting as low, as light and as quick as possible.
IE
Stripping out all rear seats, spare wheel etc. etc..., and put in bucket seats, get a BMC Induction kit, possible future manifold etc.., chipped,

Here are my options:

Keep Black 17's and buy Novitec front bumper or Novitec splitter.

OR

Get WHITE 16" lightweight alloys with 195/40/16 tyres eiether (Team dynamics/ Speedline - Corse/ Compotive racing wheels etc... and buy splitter.

OR

Get BLACK 16" lightweight alloys with 195/40/16 tyres eiether (Team dynamics/ Speedline - Corse/ Compotive racing wheels etc... and buy splitter


What are your opinions?
Will going down to 16" with 40 tyres make a big difference? or un-noticeable?

I am keeping this car for 2 years now untill I finish UNi, as this is only £500 on insurance, then after finish Uni will be 25, etc etc.

Me puzzled on options
