Hillclimb/sprint suspension options for non-sport

[hillclimbclio]

Hi all, I'm in the initial stages of building a budget(ish!) 1.4 16v mk2, primarily for hillclimbs/sprints with a few track days hopefully thrown in. Car will also be used a fair bit on the road but comfort not a priority. Budget of MAX £800

My shortlist so far is :
- Bilstein b8 dampers - not sure on springs. Recommendations welcome
- ST stx coilovers
- modded GAZ GHA coilovers (60mm bolt spacing modded to 58mm to fit my hubs)

Any experience of these setups and/or other recommendations. I'm open to suggestions.

Thanks
Matt
