Danza's rule of modding - never do anything you can't undo. I've always stripped and punted a stock car and the bits separate.
Is it going to feel like £10k well invested? Or just your Golf, but faster?? Not money well spent IMO.
I know people love modding to the extreme and seeing how far they can push things, fair play, it's their money. I'm firmly in the camp of 'if you want a fast car, then first buy a fast car'.
This is my approach. You can pour £10k into a GTI and at the end of the day, it's still a golf GTI, but faster & sharper.
I like to do mods which give the best bang for buck. Eg: panel filter, pre-cat delete, engine mount insert, remap, Superpro wishbone/ console bushes, lowering springs, R32 brakes and decent tyres
That lot gives a boost in all areas (power, handling, feel, sound & braking) without breaking the bank
You can spend £700 on your car and get a big smile, spend £10k and still only get a big smile. The novelty wears off eventually regardless. . . .
You get to the point where you end up spending hundreds of pounds just to get a small performance increase. As Hurdy says: the law of diminishing returns (not that it stops him
)
ETTO at the end of the day
