Axle center

I'm in the process of fitting an IRS in my +4 chassis, but I need to know where a live axle would be centered at ride height, so I can match that location for my IRS

Basically decide on your rear ride height and work it out from that. Not particularly difficult to do.

I think some recommend you run an inch of rake, so the back of the car 1" higher than the front.

Level with the centre of your wheels.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

OK I guess I asked for that.
I'm looking for positioning front to back as well.

Centre of the wheel! Or centre of the wheel arch?

What's the wheel arch got to do with it? You can stick them where you want once the wheels are on. Front to back is nothing to do with ride height either, the body height from the floor is the ride height and is governed by the shock absorbers and springs and the size of the wheel and tyre combination. The angle of the driveshafts will be all that is affected on an independent setup

The centre of my wheels is 10" off the ground, thats with a 13" wheel. Position wise, you want the weight as close to the centre of the car but the tyres will have more grip (or in fact leverage over polar inertia) if they are further away.

Installed mine so that the halfshafts are at right angles to the chassis looking from above, built my bones so the bottom ones are level to the ground with 5" ride height.

The angle of the half shafts then depends on your wheel diameter if you are making your own hub carriers you can move the location of the bearing up or down to keep the bottom bone correct.

If you are buying this its wherever they end up.

I made my arches so they fit tightly around the wheel and are centered.
