There are companies who make a replica S2 front bumper that fits with the standard badge panel and wings, this keeps the price and work down. However, these are not exactly the same profile as the real thing.
Other companies do bumpers that fit with the standard wings but require an S2 badge panel + headlight covers, etc. I have one of those, it looks OK, is the same profile and takes all the Porsche hardware (lights, etc.). But, I will be changing over to the real thing later next year if all goes well.
One thing to watch out for if you do go down this route is the price of the S2 lights...
They can be really expensive even SH, and new they are really pricey. Unfortunately, finding a good set SH is tricky as a lot of them now have rusty fittings and broken plastic mouldings. Good ones therefore command a decent price.
(Will half the amount when I tell the wife lol).
