H&R or Eibach hub-centrics. I wouldn't go more than 20mm though.
I looked at 15mm ones for mine but I'm going to leave it for the time being.
Mate with an R27 is running 16mm spacers all round with his H&R springs. Looks mint.

Tom iirc with the Albion 197 is running 25mm all round with turinis and it looks amazing
I have 20mm on mine from ebay http://www.ebay.co.uk/itm/RENAULT-M...Wheels_tyres_Trim_Nuts_ET&hash=item43a53f35ac
SRS ?
I'd advise you to go to Specsavers or perhaps just learn to read. Maybe you just need an early night
If you want the safer option IMO, go with expensive option.
The cheaper will - that's WILL - require longer bolts due to the 20mm disconnect from the wheel to the hub.
