As above. I intend to use a MAC#1 just for general road use, not really for track days (maybe the odd one).

Thinking logically, I think its a "faster geared" steering rack so the wheels turn more for a given steering input. But why, whats the benefit?? any downsides?

pros of a quick rack is its easier to correct a slide, without frantically turning the wheel five times etc. Down side is obviously its more sensitive, you'll sneeze and find yourself on a new road

My personal preference is as quick a rack as possible, but you really need to try it and see.

I have a quick rack and a tiny steering wheel so it's very sensitive. However for me it just makes it seem even more like a go-kart and I love it

I agree with Mark - get used to the car then upgrade later, if you think it's necessary.

I have a 2.4 turn rack and my car is quite twitchy; if you are distracted by, say, a fine young lady in a short dress you'll probably drive into the gutter!

Steering at parking speeds is also heavy work.

Wouldn't be without one myself

nor me!

stock sierra power rack is 2.8 turns lock to lock which is pretty fast by most standards and thats too slow for my liking.

2.4 turn quickrack on the 7

I'll be fitting one to mine this winter, didn't think i'd bother, but just bought an Alfa 156 - only 2.2 turns lock to lock. feels like a go kart next to the Locost (never thought I'd say that!!)

Quick racks do not make your steering twitchy!!!!!!!
They decrease the amount of turns required to make a turn, but the only reason that your car is twitchy is because of poor castor angles. Do a search for previous threads on the matter.
I have a 1.25 turns lock to lock titan rack and with 7 degrees of castor, it is magic to drive.

Now, now, don't start another argument...

My caster angles are very nice, thank you, and I have loads of self-centering (I like it that way).

Quick racks do make it a lot easier to wander on the road due to hand movement - a little movement on the wheel makes you change direction a lot quicker than a slow rack.

It's not a problem, but you do have to pay a bit more attention (as if your mind could wander in a fast-moving 7!)

So if you're easily distracted don't get a quick rack. There is a 2.9 which is in between 2.2 and the standard rack at about 3.5 turns which might suit you better for road use.

Alongside the rack ratio you also need to consider steering wheel diameter, small wheel & quick rack make very sensitive steering. If you have this combination & lots of castor the steering is very heavy.
My preference is smallish wheel, quickrack & small castor angles, as excessive camber on turning is not necessary on 7's.

Just anothers experience...

I started with a standard rack which was great on the road but hopeless on track for correcting the car.

Switched to a 2.4 rack for mostly track use which was great and fine for road use but I did tend to keep both hands on the wheel.

Now got a 2.9 fitted but not tried (this weekend hopefully) as the 2.4 had excessive play. Raw now fit the 2.9 rather than the 2.4 unless a customer requires it.
