axle swap time how capable is a std crownwheel and pinion

[fax0815]

Can anyone tell me more about the H100 axle than?
I can´t find them and they got drum brakes and are well expensive, and thats in Germany and the UK. I can find one in the UK are about 350€ which seems expensive as fuck to me and none in Germany.
By the time I got all the mounts cut bend and jiged to fit an AE86, together with adjustable link bars to set the pinion angle, I recon I spend more than a weir kit costs, and it more unsprung weight and 4,22 is a pretty bad final drive...

What ratio are avaliable? Are they all drum brakes? What pcd? How wide compared to an AE86 axle? What diameter on the cwp?

I was looking into Estima rear axles /7" cwp) as well which are cheaper like 150€, and got at least a 4,3 and disc brakes, but the weight is unreal compared to an AE86 axle, I dont wanna put any more unsprung weight on the rear as it just makes the liveaxle problem worse...

Just trying to to gater information what other people have done, how much do you recon you´ve spend on an H100 conversion?
