You will need a set of ramps but even they can bee too high for a low front and ramps usually have to be bolted down so they dont skid when you try to drive up them.
The body kit is not too OTT. Only downside are the overhanding side skirts that look like rolls of fat above skinny jeans and those triangular air intakes on the front are too much - fill them in.
The last issue is durability. ABS plastic used on OEM bumpers is flexible and high impact so it can handle minor knocks. Glass fibre is amazingly strong but not very flexible and the gel coat cracks very easily. One clumsy f*rt in Tescos and its cracked / crazed for ever. Its nearly impossible to fill out any damage without cracks coming through.
Last of all check with the insurance. They love any excuse to drop your cover when you need it and you wont get the (wasted) premium back.
