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.

[@boostedthirdgenracing]

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

[@QA1TECH]

We typically recommend starting the clicks from full soft and adjusting from there. www.qa1.net/tech-center/tech-articles/how-to-determine-your-valving-on-qa1-shocks

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

[@coltenconneway1230]

I would have thought to actually tighten the compression?

[@gregmccoy1137]

Sounds like it wants some more air pressure.

[@timothycraft5448]

More air pressure or more power.

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

[@QA1TECH]

The extension of the axle downward (rebound) is what allows the tire to dig into the track during separation. The compression is the tire moving back up into the fender. A firmer compression after the hit of the tire will help hold the tire down to the track.

[@coltenconneway1230]

@@QA1TECH right, but with when shifting weight, isn't the compression what makes the tire hit the ground? Do to the shift in weight, wouldnt a higher comp (making the compressing of the shock stiffer) be sending the tires into the ground? And the rebound, isn't that the rate in which the shock expands?

[@QA1TECH]

@@coltenconneway1230 Gotcha. We see what you're saying. Yes, you are correct. Compression is also used for what you're explaining. Both explanations are correct. We're both just looking at it in different ways. Thanks for sharing yours! It's cool to see the way other people think about it.

[@mmmmmMuffinz]

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

Ok, go ahead...

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.
