Eibach Pro-Kit on '01 Cobra?

[Iwvustang]

When I bought my '01 Cobra it had the Eibach Pro-Kit springs on it. Today I was looking around on the PartsShopper and became very confused when I saw under the Pro-Kit it said "Will not work with Cobra IRS." Is it that they don't work properly with the IRS, and thus I should take them off? I don't understand.

Eibach makes 2 kits.....one for IRS, one without. Leave them on.

I was wondering if that was the case, thanks.
