Hi guys!

 

Might be completely of here... but..:-)

 

Has anyone used a steering rack like this https://www.grannasracing.com/products/mkiv-supra-manual-steering-rack-1 in a street car?

 

Noticed my rack is sweating, and looking at maybe do a powersteering delete, if its drivable on the street that is;-) want to tidy up and remove things;-)

 

The link is for a lhd i think, but probably can make a rhd as well..

I would imagine that would be horrible and like driving a tank at low speeds !! It's not a light car, I once drove a corsa with no power steering and that was like wrestling a bull I can only imagine what it would be like with a car twice as heavy ...

20 to 1 ratio is a lot lower than stock, so whilst it may lighten what would be ridiculously heavy manoeuvring with a none pwer assisted stock ratio, you will have to turn the wheel more for a given radius turn, and it won't feel as "swerveable". IMHO on a full weight car it's strictly drag race only. You can get away with a manual rack in an RX-7, but not in a road driven MKIV.
