Numbnutz Posted May 19, 2013 Posted May 19, 2013 This is a copy of my post over on Seloc (Linky) - I've posted it here in the hope it may help others planning something similar (Honda is about 20kg heavier on the back drivers side) Well this is probably opening up a can of worms, and give more different answers but .... I feel the need for some 1 Way Nitron 46's for my S2 Honda ( I guess around 810-820 kg) - so what spring rates should I look at? (Currently on the Bilsteins (200/285?) which I feel are no good and too soft at the back). Another S2 Honda on here was corner weighted at F L = 168 kg F R = 144.5kg R L = 263 kg R R = 236 kg I've spoken to Nitron, both Guy and a girl (who I think has since left) and as per usual - I keep getting different answers. Hopefully the following will also help anyone else considering 46's. Nitron said the following * No need for lock rings - can cause corrosion, use a blob of silicon, or some threadlock. * No need for Adj eye ends unless its a race car and you want to tune the suspension more so. * Valving is the same between Fast Road & Track Day, so pretty generic * S2 2013 spec has helpers on all 4 corners * Might be an idea to use the Nitron grease and o ring kit Spring rates: (S2) Fast Road = 400 / 475 Track Day = 450 / 525 Honda add =25-50/ 75-100 more than these depending on Fast road or Track focused. Guy suggested 'trying something like' 450 / 525 or maybe a bit higher Although at the time, I had in my head 475 / 550-575. After lots of Q's I'm now edging towards 400/550 or 425/600. New springs are £60 a corner with the hassle of refitting and re-geo etc - so I'd like to get this pretty close first time. What will I use it for? * I want to do around 8 track days a year, * Be reasonably comfortable on the road (similar to present), * Not have problems in the wet, (because its too hard etc - in this country its probably better to factor in its always wettish) * I will be running 195/205 & 225's tyres (AD08/R888/A048) * NMB Toelinks * Want a compromise between Fast road & Track Day, without making it a pain to use on the road (must still be fun on the road and ok in the wet). So, who has a S2 Honda, preferably with 46's or an S2 with 46's and 1. What spring rates do you run? 2. What ride heights (if you know)? 3. Would you change the rates, given the chance? Here is a starter of what I've gleaned / been told so far: S2 Damurphster ...... 400 / 475 – Honda: 40's Guy said 400 / 525 for fast road Honda Mtbr ............. 400 / 550 – Duratec: Was 475/550. 113/123 Rheight (475/550 oversprung frnt? 116/125mm rh) Chris Randall/Hof 400 / 550 - S2 Revalved and Reshimmed (Need reviews/feedback) Dipper ........... 425 / 550 - Honda: Spot on for road use, no TD yet. Guy recommended .. 450 / 525 – Honda: for Fast road/Track still good in the wet Chris Randall/Hof 450 / 600 - S2 Revalved/shimmed. More track focused (or 425 Fr)(Need reviews/feedback) Muu has .......... 500 / 600 – SC Honda: maybe a touch soft on track might be damping DR H ............. 500 / 600 – SC Honda: wouldn’t change it on good roads -(bad on rough pot holed city) S1 Middo ............ 400 / 475 – SC Honda: 40's not 46's MilesH ........... 400 / 475 – Honda: (770kg) much happier, uses road tyres on track Turnamere ........ 400 / 475 - Rover turbo SIMT ............. 450 / 525 – Rover: Thinks could have gone higher TurboToaster ..... 450 / 650 – SC Rover: too firm 400/550 may be better Stimpy ........... 500 / 550 - Honda: wants to go firmer 625 or 525 / 650 X27EVE ........... 500 / 650 – 111s: Brilliant ride on road (-2Rear, full soft front) Benja ............ 550 / 700 - 40's +helpers, wishbone rose joints, Like it on circuit, bit OTT on road S2 Non Nitron Russelld ......... 450 / 500 - VHPD: Dynamics 2 ways JonnyFox ......... 450 / 550 - Yota: 46 2 way Ohlins. Bump 10 Rebound 18 (wet or dry) 799kg I'll update the above list as ppl comment Comments / views / experience of these shocks/settings please ... ta
russelld Posted May 19, 2013 Posted May 19, 2013 450 / 500 with Dynamics 2 way adjustable dampers / K series VHPD. Not as harsh as you would think . Bump and rebound are both set about the same and about middle of the adjustment range, good for road ( can be crashy on bad B roads ) very planted on track.
jonnyfox Posted May 21, 2013 Posted May 21, 2013 46mm 2 way Ohlins (Thx to JSR/Aurok Spec) F 450 R 550 Bump 10 Rebound 18 (wet or dry truly awesome damper) S2 799kg (hopefully)
Steve J Posted May 22, 2013 Posted May 22, 2013 425f 500r with car weighing approx 830kg Had them years so can't remember what the old suspension was like other than very squishy
