Disabling 4ws in 93 Telstar TX5

[dirty hands]

the answer is no there is a lot of components and electronic considerations

have you had the edges rounded in the wheel arch

special tool just fold the metal into the wheel arch for clearence
saw a web artical about it or flares made ?

$ costly

thinner mags?

you would have to set the car up with the model without the 4 wheel steering

costly and needs an engineers certificate

you have to be sure the car handles corners and brakes safely at all times
