CTE COS34001
Bring back the 911 (997)’s original precision.
A complete chassis and suspension restoration kit for the PORSCHE 911 (997) range, including the 4.0 GT3 RS. 16 pieces covering front and rear control arms, tie rods and stabilizer links replace aged rubber bushings and ball joints in one go.
Steering shake, vague turn-in, chassis noise?
These usually come from hardened, aged rubber bushings and ball joints. Don’t let them lock away the pure driving pleasure of this classic rear-engine sports car.
High-speed shake
A slight vibration in the steering wheel at highway speed.
Vague turn-in
Cornering no longer feels as precise and sharp as it once did.
Chassis noise
Annoying rattles and knocks over uneven road surfaces.
The chassis works as one connected system.
Replacing a single control arm can make things worse: the stiffness of the new part speeds up wear on the old parts around it, leaving the car feeling uneven and often sending you back to the shop for more noise-hunting and another wheel alignment.
One complete refresh
Front and rear control arms, tie rods and stabilizer links are all replaced together, removing play and aging in a single job.
Pure European pedigree
Built to replace OEM specification, balancing the firm toughness of a German sports car with everyday road comfort.
Precise, safe, durable
14.6 kg of solid craftsmanship that stands up to spirited driving and restores a steering feel with no lag between wheel and road.
Specifications
Frequently asked questions
What is included in COS34001?
16 pieces: front and rear control arms, tie rods and stabilizer links, with a total weight of 14.6 kg.
Which vehicles does COS34001 fit?
It fits the entire PORSCHE 911 (997) range, including the 4.0 GT3 RS.
Why replace the whole set instead of a single part?
The chassis is a connected system. Replacing one part makes the stiffness of the new component speed up wear on the surrounding old parts, which leads to uneven road feel and possibly repeated workshop visits and wheel alignments. Replacing the full set in one go saves repeated disassembly and alignment labor.
What are the signs of aged bushings and ball joints on a 911 (997)?
Common signs are steering wheel vibration at highway speed, less precise turn-in through corners, and chassis noise over uneven road surfaces.
What specification is COS34001 built to?
COS34001 is built to replace OEM specification, balancing the firm toughness of a German sports car with everyday road comfort.
Do it once, at the big service.
Rather than waiting for parts to fail one by one and repairing them in stages, address the front and rear axles together during a major service. You save repeated alignment and disassembly labor, and feel the tight, solid, planted character the moment the car leaves the shop. CTE European Chassis Specialists engineered this kit for exactly that.
Carry the classic 911 (997) into its next decade.
