    HPF M3 loses control at the strip

    We just received these videos of an HPF turbo M3 which lost control at the Irwindale 1/8 mile strip and ended up going into the wall. The car looks like it is running bias-ply slicks with radial street tires up front. This may have contributed to the driver losing control as the general rule is not to mix due to instability up top. Additionally, once the car starts to sway it looks like the owner stays in it and then tried to brake too late which causes him to lose it. Hopefully we will have more details on the car and the setup soon.

    Damn, that really sucks. Hope the driver was alright. Looks like bias plys out back mixed with radials up front. Not a good combination.

    Edit: Duh..should have read your post first Sticky. Agreed, I would think the mix of tires might have had something to do with this.

    Different sidewall loads basically.

    Here's a quote from Dunlop: "Bias and radial tires have significantly different dynamic properties. They deflect differently, create different cornering forces, have different damping characteristics, as well as other differences.

    I think in this case when the load went off the rear slicks, the load transferred onto the front tires which got traction and swerved. The radials are better grip with the sidewalls for turns, thus when getting the load transferred the radial sidewall grabbed and caused the car to swerve alittle. After that its tough to regain unless you really know what you are doing.
