My suspensions settings are still set at 2 (front/rear) from factory. What setting do y’all run on the street, road course, and drag strip?

I think this should be in the second gen forum, not the first gen...

Anyway, I run F/R  street = 3/2, fast road 5/4 on my 2013 Laguna Seca.

FYI, There is a difference between the Laguna Seca shocks and the stock BOSS stocks, with the LS being a bit “stiffer”.

They are all Tokico Illumina shocks, which when you adjust them you change both the compression and rebound settings. They are basically the same type as the ones Steeda sells in their suspension kits for the Mustang GT.

I didn't know they have different shocks , I will try some adjustments. Thanks again for your expertise  :)

Rear Shock tuning tip of the day......

What to do when the eyes are not good enough anymore to see those teeny tiny little clicker numbers on the top of the rear shocks....

Send the wife with the good eyes in there!

BOSS 302's are like a fabulous WI cheddar. Both get better with age and you buy them for your enjoyment, not as an investment.

Update to rear shock tuning post....

Somehow I get the impression the wife doesn't care too much for climbing in and out of the trunk every time I want to change a shock setting so she bought me a present.....a good old fashioned magnifying glass from the Dollar store. Great idea! It's kind of like those AARP offers you get in the mail all the time. No matter how much you deny it, you eventually give in.....

Anyway, it was a beautiful sunny upper 60's spring Saturday here in Michigan. A perfect day for testing out some shock settings (great timing for the magnifying glass too). We put on around 200 miles over a variety of road configurations incrementally adjusting front and rear settings in a multitude of combinations from one extreme to the other just to experience the effects.

After narrowing it down, we concluded at the end of the day Hopey's shock settings in the beginning of this post were pretty much spot on....

Thanks Hopey, we had a blast validating your results! Can't wait for the next ride.....

Marty

Marty,

Someone makes an adjuster knob that clips on the top of the adjuster, I always mean to buy a set for the rear. Those damper settings seem to work for me. I played with them a lot last summer up around Fontana Dam, NC. US129 “The Dragon” seems to like 1 click less on the rear, probably because it’s so bumpy, allowing me good traction out of the sweeping U bends. Cherohala skyway, one of my favorite roads is definitely a 5/4 F/R.

I played with tire pressures as well, using a laser temperature gun to measure tire temperatures across the treads. Second June in a row up in the Smoky Mountains. The original Pirellis liked running HOT around 40/38psi F/R, which translated to 35/33 cold. I should say these tires seemed very sensitive to pressure, quickly affecting the balance of the car. A 2 psi increase in the rear quickly changed the handling from relatively neutral/slight understeer to oversteer.

I swapped to Michelin PS4S last year, all be it one width wider than stock. They seemed to like slightly lower pressures, (38/36 HOT, 32/32 COLD) and on the whole were less sensitive to pressure changes, with the handling of the car remaining much more predictable.

Several of the guys I was with were driving the newer GT350s that had the Michelin Cup Sport 2 tires. They had great grip during the day when hot, but the balance of their cars in the damp or when cold in the morning wasn’t nearly as nice as the BOSS with the PS4S tires.
