Points for non-OE rear suspension

I have a factory 4 link suspension with a Watts link. If I upgraded to aftermarket replacement pieces, how many points would it be? I read 10 points per corner. So is it 20 points? or 10 for each corner and another 10 for the watts link making it 30? or 10 for each component making it 50?

At 10 points per corner per component it would be 20 points for the non-OE upper inks, 20 points for the non-OE lower links, plus 10 for the Watts.  I believe this to be the correct ruling but others have gotten different points assigned in the past.  Note, I am not tech.

Sooo...we've gone through Tech twice with our Mazda with aftermarket rear trailing links. We were assigned 10-points in 2017 after pointing out to Tech at Sebring what we had. 

The specific item(s) to which you are referring is "Suspension component not listed in table, non-OE". These are listed at "10 points each" on the 2016, 2017 and 2018 Tech Sheets. While there was a language change to "per corner" in the BCCR for 2018, Tech assigned a pair of rear trailing links at 10 points when we tech'd for 2018. We very specifically questioned Dan about this, and he clearly and definitively clarified to us that these were based on a set or pair. 

Our interpretation based on two straight years of being assessed for a "Suspension component not listed in table, non-OE", but supplied as a "component" in a "pair", is that they are 10-points. I'll be happy to post our log book pages for the last two years for those who claimed that we "didn't understand" or were "rule lawyering" the BCCR (not Ron_e).  

So you should get 10 for the uppers, 10 for the lowers and 10 for the Watts link for 30 total points.

We have a pair of non-OE control arms and a pair of hubs on our car, I will see what tech has to say this weekend and what is assigned.  It does seem to be confusing.

Hopefully the info I've given will be helpful.

On a side note, if you have a set of AM LCA's, why not box them and just take the points for material?

If you have a first gen RX7 the correct answer is 10 points for a third link, and 10 points for a panhard bar that is how to make one of these cars handle.

 

Sadly nowadays if you want race quality parts for these you are left with making them yourself.

1st gen Rx7 with factory lower rear arms...As said.  Add a panhard and a trilink.  Find a way to remove the bushings from the upper arms to be any material...like foam, soft rubber...what ever it takes to get rid of the rear bind.  The 1st gen becomes enjoyable to drive at the limit without worries of a snap oversteer

 

Cheers
