seen some lovely carbon sparco pedals with rubber inserts, would these class as enough grip for sva?

I dont think the dimple type rubber is enough for the SVA Has to be total IIRC. Is this the type you mean?

rubber dimples should suffice as anti slip. mk just weld dots on the pedals ffs! they're e marked afaik, but will probably be too big for the pedal box. there's only just about enough clearance as it is, while still allowing heel toe when the mood takes you.

i'd not bother. anything bigger than the pad there already, and you'll cause yourself trouble. it's not like anyone's going to be looking in your pedal box anyway.

they are nice, but probably better on a plinth on the mantle piece.
