My understanding is all 3 series from E36 and E46 has same front arm suspension set up consisting of the lower control arm (or C arm you might call it) and tie rod wiht variance on the bushings (offset or in the middle). Starting from the E90/E92, the 3 series have the same front arm suspension set up from the 5 series.
I am not referring to the strut/spring set up.
Iam open for correction for any inaccuracy here.

No, the E46 CSL does not have the same front suspension arms as the E36. Those on the CSL are different to the E46 M3 and the Z4M Coupe adopted these also.
Here is an extract from BMW's press release on the Z4M Coupe.
"Suspension and brakes - derived from the M3 CSL
The Z4 Coupé’s front suspension consists of a spring strut structure front axle with forged aluminium track control arms, twin-sleeve gas-pressure shock absorbers, rack and pinion steering and an anti-roll bar. The central arm rear axle also uses twin-sleeve gas-pressure shock absorbers and an anti-roll bar to provide the best link between the rear axle subframe and body of the car to achieve the smoothest ride from the stiffest possible chassis.
The M Coupé takes things a step further. Engineers from BMW M have transferred brake and suspension technologies from the renowned M3 CSL to give the new Z4 M Coupé superb handling and braking characteristics. Drilled and vented 345 x 28mm front brake discs and 328 x 20mm discs on the rear are mated to the CSL’s floating callipers. This ensures that the Z4 Coupé stops from 62mph in just 34 metres. The drilled discs not only aid cooling and braking but also reduce the unsprung masses of the car by three kilogrammes, thus further enhancing the car’s handling capabilities.
In the same vein, M3 CSL suspension components are adopted. For example, the single-joint front axle with McPherson spring struts, forged aluminium track control arms and separate mountings for the springs and dampers. All were developed on the punishing northern loop of the Nürburgring and offer the Z4 Coupé a firm, yet compliant, ride.
Top speed is electronically limited to 155mph. However, the speed restriction doesn’t stop the new Z4 Coupé posting a faster time than both the Z4 M Roadster and M3 Coupé on the infamous northern loop of the Nürburgring, achieving a time of less than eight minutes and 15 seconds – only 20 seconds slower than the scintillating performance of the M3 CSL"
