Will these brakes fit a wrangler JK with 20x10 aftermarket wheels with 4.79 backspace and -18mm offset?

Based on the manufacturer's technical specifications, the TeraFlex Delta Front and Rear Brake Kit should fit your setup, but there is one specific measurement you must verify.
Will 4.79" Backspacing Work?
While 4.79" is extremely close to the 4.75" limit, this measurement determines how much room there is between the back of the wheel spokes and the face of the brake caliper. Because your wheels are 10 inches wide with a -18mm offset, the deep "lip" of the wheel usually moves the spokes further away from the hub. However, even with large 20-inch wheels, TeraFlex strongly recommends using their downloadable Wheel Fitment Template before purchasing. This is because the internal shape of aftermarket wheel "barrels" and spoke designs varies significantly between brands.
Your diameter is perfect, but your backspacing is right on the edge. Because of that 0.04" difference, you should print the TeraFlex fitment template and check it against the back of one of your 20x10 wheels to ensure the spokes won't hit the new calipers.

SKU # 4403450 ON THERE WEBB SITE THEY SAY THIS KIT WILL WORK A JT BUT YOU DO NOT IS THIS THE SAME KIT AS i LISTED THE SKU # 2023 JEEP GLADIATOR

You are correct, this is the same part number (4403450) for the JK/JL/JT for the 5x5 bolt pattern. It's a website entry error that I will reach out to my team to correct. These **DO** fit the JT.

Would these work with the 2013-2018 18" Sahara wheels?

Yes, they would.

Does this kit really weigh 188.7lbs? Four calipers, four discs, and a 100lb dumbell?

Hi,
Will this work with your Rubicon Xtreme Wheels?

Sorry we have not tested their fit. Teraflex states a required 4.5" of backspace or less, which the Rubicon Xtreme falls .25" short of that requirement. Our apologies for any inconvenience.

Do all JK models require the brake booster upgrade, or is it just certain production years? (Ex early JK's)

Teraflex recommends it's use on all JK model years. Thanks for your inquiry.

will this kit work with jl rubicon wheels

No, it will not. Teraflex advises for wheels with backspace of 4.5" or less. Factory Rubicon wheels are either 5.71 or 6.0 of factory backspace so it will not clear the brake system. Sorry for the inconvenience.

will this kit work with stock rims

No, it will not. Teraflex requires a wheel of 4.75" of backspace or less. Factory JL wheels have backspace ranging from 5.8" to 6". Sorry for any inconvenience. Thanks for your inquiry.

I would buy this kit for a JT Gladiator, do I need to replace the rear ebrake cables?
In case, are they available from Quadratec? Thanks a lot! Dan, Italy

No, they do not need to be replaced. Thanks for your inquiry.
