Dr30 Suspension

[andylaurel]

Has anyone here had any experience with dialling out the Neg Camber and correcting the Toe on DR30 IRS?\

if so please hook me up with info

Careful, it is not swing arm IRS. More like semi trailing arm IRS from memory.

It's a semi-trailing A-arm. Same as 1600 / 180B / 200B.

If you lower the car you will get negative camber, and toe-out. The camber can't be fixed AFAIK, but you can get offset bushes for the pivot point of the A-arm to correct the toe.

Yes, lots of experience. But first you need to face up to the reality that you won’t be able to buy an off the shelf solution like you can for an R32/33/34.

well there is one off the shelf solution but it costs $3360 pillowball rear lower arms. http://www.powerplayimports.com/index.php?...list&cat_id=131 other than that a custom job is the only way to go. here is a few pic of the DR30 and HR31 racecars rear setup

You can’t simply order a $123 camber kit to adjust the camber and there are no off the shelf toe adjusters available. You will have to make, or have made for you, some parts and then modify the mounting points on the sub frame.

If you are prepared to do that yourself or pay for someone to do it, then we can continue. Let me know.

my AE86 had an adjustable 5 link rear end in it so im no stranger to the joys of rose joints!

Thanks for your help guys, im going to compete in the Qld round of Superdrift and then pull apart the rear sus and try and correct it.

Do i change the mounting points on the subframe itself? The pictures are not all that clear to me.

PS i'd love to see more pics of those race cars to get some ideas!

AE86 = piss easy, live rear axle.

IRS, strut based = much harder

The trick is changing the location of the inner mounts of the lower control arms. This means weldng brackets onto the subframe with 2 dimensional adjustment. Pictures won't help much, as it's all about the achieving the correct geometry, to do that you really need the precise dimensions. Then test the toe and camber change through the full suspension movement range.

The best I have seen is the ex Gibson R30 and R31's, if you get the chance pop along when they are in your area (hint Skylines Nationals). I have some pictures around, if I find them I will post them up.
