Thought of noting down some of the upgrades I’ve done to the car. I know the E30 is not popular as a tuner car or a modern classic in SL, but hey, this may help someone someday. I had a forum thread which I religiously updated on a different site, but the whole site disappeared with all my build/fix history L
One of my favourite upgrades and one of the absolute must do`s of anyone who is after a more enjoyable drive out of an E30 – replace the factory power steering rack.! The standard spec rack is 4 turns lock-to-lock which just too slow and mundane.
I`ve replaced with a unit from a BMW Z3, which is ‘THE’ quickest steering rack (linear ratio, not progressive) which would bolt in to the E30 chassis without modifications. Rack-ends, hoses, reservoir - all these got replaced which completely transformed the drive.
Cleaned and painted the rack before fitting, some before and after pics:
After:
Edit : Found some pics of more goodies that went in :
Holden Barina steering linkage modified to fit the longer neck of the BMW Z3 rack (god knows who found this mod first, but works like a charm for a factory finish ) :
More power steering related bits and pieces that got installed:
