Sizing help BBS

Hi All,
I'm looking at a set of BBS's can anyone tell me if BBS RS RS038 R15 15" 7J ET25 5X114.3 3 PIECE SPLIT RIMS ALLOY 
Are a suitable size for my MK1 gti 83? And whether I red spacers? Suggested tyre size?
Thanks in advance,

Well 5 x 114 wont fit, you need 4 x 100 so will require some adaptors, which will push the wheel out, and as its already wider and with a lower et than standard i think you might have issuues on the front. Unless anyone knows better.

You need 4x100 ideally. A set of rs001 et25 would be perfect

Thanks guys, I appreciate the advice.  The search for BBS's continues….
