Jimny suspension questions

I have a 2001 Jimny 4x4, 5 spd. w/ left hand drive. It is equipped with Dobinson's 2 inch lift suspension, 9500 lb. T-Max winch, ARB winch bumper, Lightforce lights, running 215/75/15 Fedimas.
I am interessted in adding 1.5 inch coil spring spacers.

Dave from Bits4Vits gave me some really good advice, but suggested I run it by some Jimny professionals. So let me know exactly what else will be needed with this. Thanks.

Adding 1.5 spring spacers may cause your shocks to bottom out over alot more when going over bumps, so either longer shocks MAY need to be fitted or shock relocation brackets on the rear with shock extensions on the front. Also when lifting over 2" you will need some form of castor correction, this can be achieved with either castor correction bushs or corrected radius arms and you will need longer/adjustable panhard rods to keep your diff in the factory possession.

Thanks for the help Monkey. That is pretty much what I heard from Dave from Bits4Vits so it was good to have that backed up.

I'm sure castor correction bushes would probably be the least expensive. How do you know what to ask for exactly? Do all castor bushes correct to the same degree, and if not, how do you know what degree you need?

Hi Nickey

You made it here then? These are the Jimny experts... I've always been a Vitara-man

I am 90% sure that all the bushs are 3deg cator bushs and any less than 3 deg over 50mm of lift they are pointless and more than 3deg they will fowl on the tie rod.

Pics of what mean.



Any more castor on the bushs and the rod will hit the diff.



There is no load in the spring there and as you can see the castor is still out by 1deg at the height of 80mm. In the ideal world longer radius would be the best thing.

Also get rubber castor bushs if you can, they will flex better and not bind up when the front is flexing like my polyurethane bushs.

"I am 90% sure that all the bushs are 3deg cator bushs and any less than 3 deg over 50mm of lift they are pointless and more than 3deg they will fowl on the tie rod."

The tie rod (track rod) is attached to the hubs, the hubs are on either end of the axle tubes, the diff is in the middle of the axle tubes. Therefore any adjustment to the castor angle, with bushes or corrected radius arms, won't change the distance between the diff and the tie rod.
