CT Tiger,
one of the design floors of the tiger was the position where the rack was mounted and the angles of the steering arms to accomodate it. It produces negative ackerman geometry with impacts on the handling and truning circles.
Dale A of dales restoriations offers a kit to mountan MG Midget rack and uses MGB steering arms that quicken the rack and reduce (not eliminate) the ackerman issue.
I believ he isn ow offering complete new front X members with coil overs and a custom rack too.
