Trailing Arm Differences
Discussion
Having both S2 (described by Adrian Ven as S 1.5) and S3 offside trailing arms availabe I toook the opportunity to compare them. I have seen photos/diagrams in the past of individual arms and heard about the differences but saw this as an opportunity to illusrate the differences.
The different mouting points for the shock absorbers are clear to see as is the adjustable inner mount

Hi All
I should have asked if the toe adjustment make a lot of difference to the car, I have been looking for the factory spec for this, could not find it, I know someone will know it. I would think if the chassis moves it could be used to bring it back but you can only adjust it it one way unless it had 10 mm of shims and spacers in it.

In the days of the factory...IF as an owner of an S1-2 you ordered a trailing arm from the factory, they came as a pair of S3 arms, my customers paid for one arm and all the associated bushes, shims etc for 2 arms, AND shocks/spring to suit the S3 setup AND you got the second arm FOC (you were required to send the old arms back to the factory).
I know I have done the conversion in the past (as in the factory method) but unless you already have spring seat adjustable shocks, then that is something you need to dial into your budget.

The difference across the models of trailing arm relates to how the shock is mounted onto the trailing arm, this moves further back, There are 3 fixed track versions (S1/S1.5/S2 the S2 has the S3 shock pick up point), eventually you get adjustable S3 and adjustable with wider track S4/V8S...on the 3 fixed versions there are different seats heights on the shock (IMHO same spring) allowing the difference leverage points on the arm to be set correctly in relation to the car ride height ... tramping creates a torque twist in the 2" tube ( my thoughts are that IF the weld seam of the 2" tube happens to be at the bottom, you get accelerated rust related failure...I have seen them split in a linear fashion with too much regularity for that not to be the cause) and TVR put the mounting to a stronger place on the C section, with a gusset over the back.
So cars with adjustable track need the correct matching shock setup, or to add the adjustable track arm you need to have adjustable spring seats.
