S10 Xtreme LS3/T56 Build

[Lonnies Performance]

Here are some updates after a few hundred miles....

The tach & speedometer function flawlessly.
I hid an LED shift light in the AC vent, which matches the 6500 rpm tach reading.

Front suspension has worked out very well. I was concerned that such a wide front tire (305 mm) may tram on uneven roads, but it tracks straight & there is no pulling or darting. I believe that keeping the back space as tight as possible, along with running a lot of caster worked.

During my testing on a sharp 270 deg. off-ramp, I had a significant amount of body roll without the rear sway bar. Unfortunately the factory rear bar would not clear the center of the S60 axle. Since there is not an aftermarket rear bar made for an S10, I was forced to build my own adjustable rear bar setup. It also helped my launches from a dead stop.

Now with the rear under control, I could feel the weight transfer to the front outside corner, which was unloading the inside rear tire, limiting how hard I could accelerate out of a turn. I'm running a Torsen differential so it is pretty forgiving in turns, but the inside tire would squeal while trying to accelerate, then with a little more throttle, I could slide the rear.

I decided to try a solid 1-1/4" UMI front bar in place of the factory hollow 32mm ZQ8 bar. This helps keep the inner rear tire planted & made a ton of difference. I gained another 10 mph (now 60 mph) on my favorite 25 mph off-ramp. I can kick the rear out at will, but it is very predictable & neutral on corner entry.

I experimented with dropping the tire pressure a few increments (from 30 down to 24) & while it helped, it did not make a huge difference.



Now I'm questioning if I should have went with the 850 lb front springs, but currently it rides pretty nice.

There one of those on the interstate near me... inevitably, when I approach it, the guy in front of me wants to go 25 LOL. it’s 15 minutes of driving to turn around to go try it again.
