13x8 alloys RB Rota alloys

[WM-S12]

I'm curious as the the offset is 4x114.3 and says PCD is 4 ET

Can get them new for £300 from rare rims but I've no idea how good or lame an s12 would look like sitting on some 13's. ( would it slightly lower the car or reduce response and what about my speed...no idea so I thought why not ask here as someone's maybe tried it or thought about it )

anyone with advice would be greatly appreciated.
