Tuning backbox with focus induction kit

[mojoex]

hey all, looking at a few more mods to my punto now that i've come into some money.
i'm not looking at spending a lot as uni is coming up, so just a few quick questions.

i already have a focus induction kit installed, and love the sound from it. so would this backbox be any good for sound? can i expect any performance gains? i don't want it incredibly loud when im just driving through town, or into my drive.

another thing, would coilover's be better for a 35mm lower? i have a 1.2 5door mk2, getting some sporting alloys. so would it be worth saving up a few months for some coilovers or could i just get a set of decent springs? whats the best options for lowering on a budget?

thanks all

That backbox is loud and crap for performance.

Buy a proper backbox e.g. supersprint, ragazzon for performance and a subtle note.

Eibach do a pro kit which is ~30mm drop, or a sportline kit which is 45/35mm drop.

They are fine on standard dampers and IMO better than the cheaper coilovers available on the market.

cheers for the reply.
how much would a ragazzon backbox be? and the 30mm eibach springs?

~£200 for backboxes mentioned (super maybe a bit more)

£150 for the springs.

I've got uni coming up and I disagree with spending that amount of money for a deeper sound. I've got a universal backbox on which sounds well nice. It costs me about 2bhp but its a 1.2 8v, i didn't buy it for power
