I own an RC46C/A6 (VTEC 06 ABS). I'm about to upgrade my suspension (both front and rear). I will replace the fork springs with ones from RaceTech and also install the Gold Valve kits (for compression and rebound). At the rear I will replace the stock shock with a HO605 from ohlins (external reservoir, hydraulic preload, compression and rebound damping adjustable).
I ride on the street (often at quite a spirited pace). Most of the times I ride without luggage, but I also do a couple of week-long trips each year with side cases and a tail-pack. Most of the riding I do is on twisty back-roads, where the pavement is at some sections very good, and elsewhere far from perfect (bumpy, cracked, and / or slippery). I weight approx 100kg (220lbs).
What spring-rates would you recommend? Having read this thread I'm leaning towards either .95kg/mm or 1.0kg/mm front, and 19.3kg/mm or 20.3kg/mm rear? The HO605 shock comes from ohlins with a standard 17.3kg/mm spring; I guess this is totally inadequate (or am I wrong)?
