Default Tuning with Inserts

I'm a veteran racer who was out of the hobby for quite a while, when pan cars ruled. Now I'm back, and I'm very new to the touring car scene. The one thing that I haven't been able to find the answers for is when to tune with your inserts.

How do you know when you need to run a firmer or softer insert, given that you're already running the "hot" tire for a particular track ? I've always been told, "Run the Pits with the Echo Blue" at this track, or "The Sorex 36R with the Yokomo Medium is the ticket". How do I know that this particular insert will work well with my chassis setup?

I asked David Spashett once on TTT, and he said that he just tries different inserts and gets a feel for what works best. Well, I respect his opinion and understand that he doesn't have a set method for determining insert selection, but I don't get my stuff for free, and I don't have an unlimited budget.

Anyone have a set method for tuning with inserts?

I just use what works! Basically a softer insert is going to allow the tire to flex more, and contour better to the surface, giving the tire a larger contact area, and more traction. So a softer insert will give you more traction, but promote faster tire wear. Say you need more rear traction, try a softer insert in the rear. Need more steering, try a softer insert in the front. On carpet tracks, running too soft of an insert will cause you to traction roll.

I think that's the way it works. I'm sure there are other parts to the problem too, but I don't know them

Hope this helps,
Josh

I always use Yokomo firm inserts with Sorex 36R (32R for night race). For me, I think that combination is the best.

pit shimizu firm molded inserts on tamiya type b tires. they work great on dirty asphalt track. i used to install tamiya 24mm firm molded inserts but the tires wear down quickly on the sides. the inserts dont fill up the tire completely. with the pit shimizu inserts, the tires wear evenly.

Another part of the equation is "feel". A firm insert is a bit more twitchy because it responds faster (stiffer sidewall). Sometimes you need all the input you can get.
