The E36 M3 has been upgraded with a fresh Guards Red paint job and swapped in the high-performance S54B32 engine with a custom tuning package for improved track performance.

Sway Bars Replaced at Last

5 hours of tweaking led to a noticeable improvement in handling, just need to dial in the stiffness now.

New Brembos on Board

Upgraded brake calipers with stainless steel lines, now the pedal feel is a significant improvement over the stock units.

Spring Rates Sorted Out

Spent a few hours dialing in the stiffness, now the chassis is doing what I told it to – no more roll under braking.

Sway Bar Endlinks Swapped Again

Replaced upper control arm bushings with custom poly bushes, now the steering feels more precise during heavy braking turns. Shifts from stiffer to looser without any noticeable lag.

Springs are Done Now

Finally had time to thread them, now we're talking serious suspension stiffness - can't wait to throw her at the track.

Bushings In For Better Pedal Feel

Swapped out the OEM bushings for some aftermarket ones that should give me a more linear pedal travel, hopefully with better feel at the limit.

Front Control Arms Replaced

Swapped out the OEM parts with stiffer, adjustable units that should help the car turn flatter on the track. Initial ride quality feels spot on so far.

Springs Shaken Down Tight

Replaced all old springs with brand new ones, still have to bleed the hydraulic system but that's a relief after this mess.

Spent all day dialing in the correct stiffness curve, now the suspension is finally predictable on both the track and daily commute.
