stants Posted August 12, 2014 Share Posted August 12, 2014 Can anyone tell me what the standard spring rates are please? Lookiing at replacing the suspension, one bc kit lists replacement springs at 8kg/mm at the front and 6kg/mm rear, I think this may be too much.

Ash007ks Posted August 13, 2014 Share Posted August 13, 2014 speaking with some of the scooby lads on monday they reckon 8 is the best overall Quote Link to comment Share on other sites More sharing options...

Mr B Posted August 13, 2014 Share Posted August 13, 2014 On B-roads 8kg is awful, ok for track but for good handling & grip on real average roads & wet roads coilovers like BC & high spring rates are awful. Best road handling would be new struts from kyb or monroe & some custom springs from springcoil ... Quote Link to comment Share on other sites More sharing options...
stants Posted August 13, 2014 Author Share Posted August 13, 2014 Now I'm slightly confused as various foz websites recommend a 6/5 fron rear rate where as bc website is 8/6 Although I've read that that combo makes it unbarable as a daily drive. Going on weights of models the sf has the least kerb weight but highest front spring rate ? I'd have thought that it would be more in line with the classic impreza set up due to there no being much difference in weight Quote Link to comment Share on other sites More sharing options...
stants Posted August 13, 2014 Author Share Posted August 13, 2014 Mr b, Thats what I was thinking but I could do with new tops too was just trying to get the entire package cheaper as I didn'd really want to buy any in the 1st place. Had kyb's in the past and found them to be good, whats your opinion on the pedders stuff ? Sorry I was typing the reply as before seeing your other post :-D Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 13, 2014 Share Posted August 13, 2014 8/6 on a daily road car will be awful & a downgrade in handling/grip. 6/5 will be bad enough with pillow balls & stiffer rear rubber mounts. Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 13, 2014 Share Posted August 13, 2014 I don't rate the pedders very highly mainly in terms of durability as replaced a few that not been that old but dampers had failed. You get 2 year warranty on kyb's , kyb do top hats too as they are the OEM for subaru. Mix that with some custom springs from springcoil & you would have decent ride & grip in all weather & road types. kyb struts are probably about £70 a corner & springcoil would be about £55, throw in top hats & strut boot kits & you should do complete at £700ish Quote Link to comment Share on other sites More sharing options...
stants Posted August 13, 2014 Author Share Posted August 13, 2014 Do you have a link for kby's can only find stufc to fit the SG I'm guessing they'd fit but dont wat to take a chance Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted August 13, 2014 Share Posted August 13, 2014 http://bbs.scoobynet.com/suspension-12/924270-coilover-spring-rates.html check that link stanton, I stand corrected. Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted August 13, 2014 Share Posted August 13, 2014 seems 6-5 is most popular on various sites and some use 4-3 for a more comfortable ride. makes sense as guy i was speaking to uses his for alot of track. Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 13, 2014 Share Posted August 13, 2014 I'll post part numbers for KYB later as busy at mo. Won't find them in masses on internet or eBay, SG range found easily mainly as huge stock hence cheap prices of around £55 for SG. Top hat kit (front) from KYB is same for sf & sg & that number is SM5361 You can use kyb spring too and they cheaper than springcoil but obviously no custom ratings. If yours is JDM import then standard springs are stiffer than EU vehicles. You would be best pricing from local factors and you should be able get some level of trade price if handle it right. 4/3 or 4.25/3.5 is better real world ratings for BC, 6/5 ok on good dry surface but !Removed! on wet or bumpy roads, BC strut travel is also very short in travel range & not great on 4wd road cars.

Mr B Posted August 13, 2014 Share Posted August 13, 2014 Part# Struts *excel-G* Front L 334190 R 334189 Rear L 334192 R 334191 Tophats Front SM53611 Rear L SM8101 R SM8102 Protection boot/bump kit *1kit for 2 struts* Front 910105 Rear 910072 Springs *kyb k-flex* Front RC2315 Rear RA5763 No idea on your current condition/suspension problems & what your goal is. for best price you would best use KYB springs or originals if good enough order, also expect rear original tophats re-usable but up to you to evaluate. If handling big on agenda then springcoil springs would be good but more hassle & more £. Monroe do struts too & they decent struts so don't overlook them should you see a nice price.

stants Posted August 13, 2014 Author Share Posted August 13, 2014 Thanks for that, currently one's nearly dead and the rest are all saging all ovet the place so it's an emergency buy everything job and replace Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 13, 2014 Share Posted August 13, 2014 Just go with KYB springs then if want keep price decent, review tophats too as current maybe serviceable especially rears. Expect springs tophats & protection kits can be had on likes of eBay but struts are hit & miss pending on stock levels & looks like most eBay suppliers cleared them as very little struts for SF. I get them for a little under £70 & they throw in the protection kits free for full sets, just find what can and prices on eBay etc then call a few autofactors & have all details on hand & see what prices you get. Should be quite reasonable & if you do the work yourself I expect a whole set of struts/springs would be cheaper than just 1 complete strut/spring from Subaru so not bad really.
