Grintch Posted August 29, 2018 Share Posted August 29, 2018 To make sure I am clear, for ST 5 & 6: A common strut/strut car -> no adjustment A fairly common strut/multilink car (~wishbones at one end) -> -0.8 A wishbone/multilink car (~wishbones F & R) -> -1.6 Is this right, or is a one time adjustment even if you have wishbones all round?

Just one assessment. -0.8. Quote Link to comment Share on other sites More sharing options...
Grintch Posted September 1, 2018 Author Share Posted September 1, 2018 Thanks. Maybe the rule would be clearer if it said "front and/or rear"? I was interpreting "front or rear" as meaning front and rear are "scored" separately. Quote Link to comment Share on other sites More sharing options...
NorcalTT Posted October 3, 2018 Share Posted October 3, 2018 Greg - does the rear trailing arm setup as found in an e36 for example fall into the category of multi link and will then take the .8 hit? Thanks for your help. Quote Link to comment Share on other sites More sharing options...

Thanks for your help. 2) If the vehicle has an OEM suspension design utilizing an upper “A-arm” or “Wishbone” type control arm on either the front or rear suspension, a Modification Factor will be assessed. Conversion from an alternate design to an “A-arm” or “Wishbone” suspension design using non-OEM parts is not permitted (front or rear). The rule does not state "multi-link".

Isn't multi-link and duel wishbone almost the same, with the potential for multi-link to be somewhat better? I thought the intent of the rule was to separate so-so Strut based suspension from the better performing wishbone/multilink? Quote Link to comment Share on other sites More sharing options...

What is the reason that multi-link does not have a penalty when it delivers many of the benefits of a double wishbone? Quote Link to comment Share on other sites More sharing options...
