I have "race spec buddy club" coil overs and they are killing me!! I need to adjust the strut length and possibly replace the springs.

there are a load of rings and a little damper thing - but I have no idea where to start. a how to guide would be great.

johnfelstead

what spring rates do you have?

gravelexpress

8kg and 10kg according to manufacturers data

gravelexpress

anyone

From an old post by John

5kg = 279lb/inch
7kg = 394lb/inch

he said these were too hard for a road going Impreza.

no wonder yours are killing you. Sorry, no idea how to adjust them. doesn't the manufacturer have instructions? you'll probably want softer than above for a road car.

johnfelstead

Those rates are much too high for a road going impreza.

For a fast road/trackday setup i would sugest you get some 6kg front and 4kg rear springs, if you dont plan on doing any trackdays and want a good fast A road/bumpy B road setup try 5kg front and 4kg rear.

how you set them up depends on how they are constructed, if you are not sure what you are looking at you really need to take this to a decent garage who know how to install suspension, last thing you need is your suspension falling apart at speed.

thanks John and Ozzy for the replys

I gave the wrong info

they are 8kg and 6kg - according to this

http://www.aj-racing.com/BC-products...ype=Suspension

regardless they are far to stiff - to the extent that while trying to map a GEMS the motorsport garage were unable to read the laptop!

Im going to go with your advice 6kg and 4kg. I will leave the fitting of the suspension to the experts as they are going to corner weight the car, and geometric align.

Now who would you recommend for springs - they appear to be 200 and 240 mm in length

They're rather tasty unit's! Would you be selling the springs then once you have softer ones sorted out?

gravelexpress

I may as well give them away to be honest - I have never been in anything as harsh as this - they cripple you whilst driving.

and while they are no doubt perfect for a billiard table smooth jap track/road - they are of no use at all in this country and handling is impaired with them.

demon tweeks sell some 2.5" and 2.25" springs at reasonable prices in the Faulkner range.

Those damper units are adjustable independantly for ride height, so get them to use no preload other than to keep a small tension on the spring seat and then adjust height with the lower ride height collar.

gravelexpress

thanks for all the info just one more question

6kg and 4kg rated springs how does this convert to the imperial units.

Im really looking forward to getting this sorted - its going in on Saturday for full set up and then I will report back.

Well i'm still interested in the springs m8, but i'd feel like a total **** if i didn't give you SOME money for them!

johnfelstead

In order to find the pounds of a 6Kg kilogram spring you need to do the following:

6 (kilograms) x 2.22 (pounds in a kilogram) = 13.32 (pounds in a millimeter)

13.32 (lbs in a mm) x 25.4 (mm in an inch) = 338.328 (lbs in an inch)

So this would mean that an 6kg-mm spring translates to a 338 lbs-in spring

gravelexpress

you can have first dibs on them - are you sure you want them?? they are bloody nasty. where are you in the country

gravelexpress

thanks again John

20 miles north of Glasgow bud. And yes, i'm still sure i want them!

gravelexpress

wow its sorted out at last - the transforamation is amazing. no more drifting!! The rally prep garage used 325ft/lb and 275 ft/lb springs and re-set the entire geometry - THE SCOOB IS PLANTED!!

johnfelstead

excellent, glad your sorted.
