Sukira 0 Posted February 14 Report Share Posted February 14 Hi all, So my 2007 Impreza has these coil overs installed on them had 2 question. 1. General thoughts on them from the community 2. The last owner lowered it a tad too much and when going over speed bumps and bumps it hits... What height would you guys recommend raising them to for it not to be an issue but still look nice https://www.hsdcoilovers.com.au/subaru-impreza-wrx-my01-07-sti-my01-04-gd-hsd-coil~2866058 Quote Link to post Share on other sites
Jay762 1,532 Posted February 15 Report Share Posted February 15 Wotcha and welcome - I generally go for a 20mm drop all around from standard height but I like the wheel arch and wheel to be concentric to each other not closing at the wheel top / arch centre point 1 Quote Link to post Share on other sites
Sukira 0 Posted February 15 Author Report Share Posted February 15 thanks for the reply. Going to be a dumb question but the coil overs specifications say shipping height 340mm is that the standard height im basing off? Quote Link to post Share on other sites
Jay762 1,532 Posted February 16 Report Share Posted February 16 That I wouldn't know as I am not familiar with the HSD product. @Tidgy what is the standard ride height of your motor and what are you running with your setup? 1 Quote Link to post Share on other sites

Also need to take into account what the coilovers are as softer setups need more height or they bottom out. Afriad suspension setups isn't a subject im that up on. 1 Quote Link to post Share on other sites
Sukira 0 Posted Saturday at 07:09 AM Author Report Share Posted Saturday at 07:09 AM Got another general question for you guys @Tidgy @Jay762 and i know its personal prefrence but if you guys have/know anybody that has coilover that have adjustable pre-load, Whats a suitable amount for them (refering to height when you measure the coil) Quote Link to post Share on other sites
Jay762 1,532 Posted Monday at 09:45 AM Report Share Posted Monday at 09:45 AM I dont know of a coilover that does not have adjustable preload as that is what you wind on to tension the spring. This does not adjust the ride height as that is done by releasing the lock bolts at the base and winding the shock absorber in or out of the body. I set my ohlins up as per the manual. Spring preload of 198mm against a unsprung length of 200mm Shock length of 291mm Fr 392mm Rr This gives and overall drop of 20mm against OEM ride height. Quote Link to post Share on other sites
