Long awaited GS300 BBK
« on: March 29, 2021, 10:47:55 PM »
For everyone interested in my GS300/GS400/GS430/Aristo BBK
(I believe 93-04, it痴 very possible supras and sc300/soarers will fit but before I claim it someone will have to confirm)

You'll need:

02-10 VW Toureg
03-10 Porsche Cayenne
05-15 Audi Q7

NOTE: I have found car-part.com is the cheapest place to search(60 per caliper) It痴 an annoying website but yields the cheapest prices outside of local junkyards which are the cheapest (25 per caliper)

The calipers should say 17ZL and 17ZR (it痴 come to my attention most parts stores show the rotor size, 330mm instead of 17z so tell them 330mm is the caliper you need lol)
PNs 20.8432.06 and 20.8432.05 (see pictures)
(use these numbers to confirm, there are many calipers that look similar but wont work)

4x M12-1.75x30 (McmasterCarr.com PN 90128A297 - Socket cap style bolt or equivalent)

4x SCH M16-1.5x40 caliper bolts
(or reuse the hardware from Cayenne/Toureg/Q7 on the top bolt hole, the lower holes are too close to other things)
(Mcmastercarr.com PN 96144A330)

8x  Fastenal PN 0136087 or  1245L from ace hardware
 (~2.5mm thick)

30mm Roll Center Adjusters (RCA)
(available soon for $150)
Rotor specs should be 356x30mm- confirm that before ordering as there are many that are 334 which will not work.

1x 2013-2018 GS350 F sport rotor-121.44204 front iron brake rotor (Centric PN shown)

1x 2013-2018 GS350 F sport rotor-121.44205 front iron brake rotor (Centric PN shown)

**These are not gsf rotors. Is350 f sport do not work either.
Only gs350 F sport.**

For drilled and slotted use this link, make sure to request only fronts (courtesy of Kirk smith)

Stock brake lines can be used although I would recommend getting stainless braided lines as it improves feel vastly.

Make sure to take the crossover lines and bleeders off and switch sides with them (because the cayenne/q7/Touareg have the caliper on the front of the knuckle and the is300 has them on the rear of the knuckle)

NOTE: Calipers will need to be modified
See pictures in later posts.

NOTE: The Washers will go between the bracket and the caliper.

18z calipers WILL NOT WORK (without custom pads and more clearancing on the back but none for the rotor)

The OEM tie rod/ball joint fits it better.

If you purchased calipers bare the hardware to mount the pads can be had here:
