Depower Steering Rack

My question, why depower? What are we trying to achieve? Thanks for your thoughts.

the difference between power and non powered is 0.6-1?(can't remember the exact number) of a turn lock to lock or something its not a huge difference and also cleans up the engine bay!

I guess it only makes sense if you're racing the car? Can't say I'd ever want to take out power steering but I'd definitely retrofit it in though for convenience sake.

Power steering rack has a faster ratio than non-power steering rack, so if you want the feedback of non-power steering with the ratio of power steering, you need to depower.

Don't really see the point for people using their car for street purposes (from a practial point of view) but to each his/her own modifications

De=power also means less weight,less maintenance, better feel for the road & in my case more room for the turbo.

For a road car/DD, I would leave the power steer as is...after all, MX5s were never criticised for uncommunicative steering (power or otherwise)
It is however, a relatively common mod for track cars for the reasons mentioned. A 'depowered' rack is a faster ratio than the original non powered rack, results in a valuable weight saving of approx 5kg, is one less ancilliary for the engine to drive and is one less thing to possibly cause problems during a race.

Cheers

Haha lately I've been adding weight to the car in terms of both the driver and the vehicle itself although I'm trying to reverse the first one

Pretty much why weight savings aren't so important when ideally I should drop 10kg myself...

Mind you the additional weight has mainly been for the safety and handling aspect
