The car started loosing 60’ 1.40ish typically and started sliding back to 1.45 or slower. Shocks were nearly 20 year old ce 3 ways.

I have been playing with the Vikings and not making much headway. TT last Saturday 8 runs and couldn’t get below 1.50. . Worked mostly on the rears with the fronts loose on rebound and about 5 clicks of compression. Started out being really a handful out of the hole and down track . By the end of the day I can say it felt better but still a weak 60’.

I started the day with the rears 5 clicks in compression and 12 rebound.

Tried adding rebound and lost time.

Tried adding compression and started to pick up then fell off again.

Am I doing the right thing working the rear first ?

Is there a ratio of compression vs rebound I should be following?

I welcome any experienced advice

current last visit below

only 2 runs before a flat tire.
got the front to sit lower . cant go much lower with tire /header rub.
added dampening to mostly rebound as suggested .
first run is right view vid. front = c8 r18 rear = c12 r16 as you will see bounces like mad
second run left view vid. front = c12 r20 rear=c14 r18 better but still not great . rebound is 1 click away from max in front a 3 from max in rear .

I think I need the stiffer valving kit from viking as i am almost out of rebound adjustment .

tire psi was 9

the 60 in the 2nd vid picked up .07
