IRS Race Axles

[Lazarus]

i am assumiing youre talking about launches breaking axles. when i had my tranny built the person who built it also builds trannys for some very fast drag cars. he told mu it being irs it would be delicate to drag race style launches, so he made some calls to california because i wanted to go with 930 stubs and cvs. what we found from erco was they had been breaking the bearings inside the trans when putting high load on them (launches) so they had machined the inside of the case to accept dual bearings (cost of about $1000 US) the bearing problem went away,but then the spider gears started breaking and that was the last i heard. that was 1 year ago. so basically the problem moved to the inside of the tranny everytime they fixed it one place it went somewhere else.what i decided to do was just leave the stock size stubs and put good polished german cvs on. that way if ,and when, it breaks it will break outside and i wont have to pull the engine and repair something in the trans.
