So, I have new drag radials coming in. They are 1.56" taller in overall diameter than the stocks. Obviously they are only going on the rear, so my rears will be slightly taller. Unfortunately Lund Racing has said they can't correct for that in the tune.

Will this screw w/ the ABS and turn on the light? Is there enough of a difference between the front and rear diameters/circumferences?

Thx.

No problems with the ABS. You will be fine. Enjoy the added traction. If you have a manual tranny, aftermarket axles should be in your near future.

No it won't screw up your ABS but if your car is an auto it may be enough to screw with your shift points. Whipple has a device you can buy to correct it if need be.

I believe only Whipple can reconfigure a wheel change, but like Bob said you are GTG in regards to the ABS, the speedo will just be off.

You can adjust for tire size with the SCT X4. My winter tires are slightly taller and narrower than the stock tires so I used my X4 to adjust the tire revolutions per mile to compensate.
