Hi Sir. I have a 1990 musting 380 HP. I use a 4 speed manual and launch at 5, 800 RPM. I use a 9 inch slick. What is you shock suggestion? Thank you. I like the info you presented here.

do you do the clicks from full tight, or full soft? How do you know where to start from when you’re making adjustments?

So do i go POS or NEG when i need the tire to go up/down !?!?!?

[LegacyGarage]

So if i have a 4 link car that slightly rattles the tires on a tight track around 60-100ft would that be a compression or rebound issue if its that soon, my guess would be to loosen compression by the this video, car is awesome on a hot track

I wish was explanation for road racing too tkhs

[mmmmmMuffinz]

so for a drag radial on a unprepped track, I want it more soft than stiff, right?

[coltenconneway]

I think he got Compression and Rebound/Extension backwards. Comp should be what hits the track, Rebound controls the shock's extension

Someone, please correct me if I'm wrong

Qa1 denies their so called lifetime warratee. My shock blow out the inner shock tube. Split at the seam. Obvious manufacturer fault. The other shock wore the top locking collar on one side, another fault. Because I am in Australia they refused to deal with me. I contacted summit racing the vendor I purchased from and they were no help. I have branded my car with pics and qa1 sucks just to show this dishonest company not owning up to shocks that didn’t even last 2 years, 5000 kms.
