The steering rack has become a common upgrade recently though I still feel there is a lack of information surrounding the different options, so this thread can become a source for those looking to upgrade their rack. Upgrading the steering rack can increase steering feel, make the car more responsive and make the steering feel 'heavier'.
Comments are welcome and I will update the original post when new information is confirmed, however opinions should be backed up with numbers or at the least first hand experience. My initial information will be based around research conducted on sites like Mivec.co and other forums so some of this information may be wrong, so feel free to disagree but please back it up with some sort of evidence.
Stroke: The distance the internals of the Rack move side to side
LtL: The Lock to Lock of the steering rack i.e. how many turns are required to go from full lock left to full lock right
Fitment: How the rack bolts in, connects to hoses etc
Suitability: How suited the Rack is to the CE Lancer
CE Lancer
Evo 1-3 and GSR
FTO
Personal Recomendations
Based of my personal experience with the Evo 4 rack which I currently have installed and the FTO rack we installed in a mates car, I would recommend for those intending to stay 4 stud the FTO rack is an excellent option being 100% plug and play, providing a weighted responsive steering feel with no drawbacks. For those looking for the ultimate in response the Evo 4-6 rack with stroke limiters could be a good option, though I would recommend comparing lengths of the rack ends to the stock rack to ensure there will be sufficient thread in the tie rod ends when aligned. For those going 5 stud the longer arms on the FTO/Evo knuckles will reduce turning circle and responsiveness with a stock rack, I would say the Evo 4-6 is the best option, though it is important to ensure sufficient clearance between the tyre and the chassis on full lock and may require rack limiters to be used.

CE Lancer
- Stroke: 124mm
LtL: 3.2
Fitment: Stock
Suitability: Stock
Evo 1-3 and GSR
- Stroke: 124mm
GSR/Evo 1
LtL: 3.2
Evo 1 RS/Evo 2-3
LtL: 2.8
Evo 3 RS
LtL: 2.4
Fitment: Will bolt up
Suitability: Research indicates a rack from this generation will produce an awful turning circle, though they supposedly have the same stroke as stock
- Stroke: 136mm
GSR
LtL: 2.3
RS/TME
LtL: 2.1
Fitment: Will bolt up though require 2 longer bolts to fit through the solid mounts
Suitability: The longer stroke can cause problems as this cause the stock lancer knuckles to rotate a far greater angle than usual, causing the inner rear of the tyre to get chewed by the chassis in some cases. Stroke Limiters are available which will also limit the LtL. Also FTO knuckles change the arm lengths and thus avoid this problem but the 'heaviness' and responsiveness of the steering is reduced somewhat, though still better than stock. Also some have observed there being only a small amount of thread left in the tie rod end when correctly aligned, when using 4 stud knuckles.
EDIT: FTO knuckles stopped the tyres being munched for over a year on the street, however the extra stress from a trackday caused the tyres to once again be pushed into the chassis and be chewed up. As such it is strongly recommended that anyone trying this conversion uses some form of rack limiter to reduce the stroke back to the stock 124mm.
This is a common form of rack limiter used on mustang steering racks and a similar design would most likely be the easiest and cheapest solution. It is also possible that using Evo knuckles would reduce the tendency for the tyre to scrub, though this is unconfirmed.
- Stroke: ?
LtL: ?
Fitment: ?
Suitability: ?
FTO
- Stroke: 124mm
LtL: 2.6
Fitment: Bolt up
Suitability: Has been performed many times without issue, appears to be the same as a lancer stock rack but with lower LtL
