No need confuse la.
Adjustable suspension has 2 types. Hi/lo and Hi/lo/soft/hard. Generally these days both types of suspension have body shift. The H/L/S/H type I keep talking about is usually 3k and above brand new. HWL might be cheaper. Ohlins for example will cost 13k brand new. AR Racing/BC Racing about 3.3k. HWL I've seen them sell at 2.8K.
Performance absorbers (just absorbers no springs) are like APM Performax, Koni FSD, Bilsteins etc. The price varies.
Custom suspension like those made by PRS, Ftuned, RDS, they take your original suspension and modify it with their own secret recipe to give you the performance you request for. I can only quote you PRS prices because I went to them and it's RM150 per absorber for initial modification. Afterwards it'll be RM100 a piece since the infrastructure would already be there. I don't know how much Ftuned and RDS charge. PRS has their own version of coilovers too, last i saw it was 2.6k for a Honda Jazz.
So no need confuse la.
Personally if I were in your shoes and having owned a Wira A/B SE, I would go with Wira SE suspension (I'm actually not sure if Monroe makes absorbers for the SE, if they give you the 1.6/1.8 one it might be overly low in the front since the spring cup is lower compared to Wira SE absorbers) and with super stiff antiroll bars. In all the suspension mods I did, the antiroll bars were the ones that helped me the most. Then the side bars, room bar and front tower strut bar. Rear tower strut ok la, not really necessary and fender bars not so much feel. Avoid the rear upper bar at all costs - will make the car super over-steery. You won't like that.
Yeah. Jom TT then we can poison you some more.
