bimmerc Veteran Date registered: Jun 2009 Location: Alta, Norway Vehicle(s): 1992 300GE swb Portals, 85 300GD STT Cab swb Posts: 102 | New brakes I am not too happy with the brakes on my 1992 300GE SWB. I know it's an overkill and they are indeed called killeraxles. Any good reasons for not doing it. 4-speed auto trans, 4.33 axles and 35x16" tires.

Their purpose is to gain ground clearance (about 40 cm under the diffs). (G with Tibus/GfG portals a.k.a. Killeraxles vs. a standart one).

Their purpose is to gain ground clearance (about 40 cm under the diffs). (G with Tibus/GfG portals a.k.a. Killeraxles vs. a standart one). They will be my new brakes. That is my story and I am sticking to it. At least that´s what I have told my wife! And I DO get new disk brakes in the rear! My concern is whether the reduction in gearing will be a problem at hwy speeds. Should I get a 5-speed tranny or change the transfer case to a 0,87. Changing T/C seem excessive to me, but if that´s what it takes I will start looking for one. My first plan is to change the transmission. I do appreciate comments and suggestions. | ||

Don´t think it affects the highway speed that much. The LWB cabrio G280CDI on the picture was able of going 170 km/h+ BTW.do You want to put them on the 300GD or on the 300GE? | ||

If all youre looking for is better brakes, you might save a lot of money just looking for brake upgrade kits. You try convincing your wife that you need portal axles on your toy! She does not need to know the cost. | ||

bimmerc Veteran Date registered: Jun 2009 Location: Alta, Norway Vehicle(s): 1992 300GE swb Portals, 85 300GD STT Cab swb Posts: 102 | Portal axles Can anyone tell me what my rpm`s will be at 60 mph (100 km/h) when i install the portals and 35" wheels? Today, with 33" wheels I have 3400 rpm and 60 mph The portals gives a reduction of 1.16 in order to compensate for the bigger tires. I believe the stock tires for the 300GE is approx 30.5". The gear reduction required should be 1.15 so 1.16 will give give some spare torque. I initially thought I would need 4000 rpm at highway speeds (60 mph), but realise that i would be better off than my present setup. Can`t find a table that will show me the numbers. | ||

Will have them around March 1st, but won`t have them installed before May due to snowmobile season taking priority. Unless I manage to squeeze it in. Having them sitting in a box in the garage may be tough, though! Surely will keep you posted. | ||

Gilamonster Veteran Date registered: Sep 2013 Location: New Mexico Vehicle(s): G #1 (mix of a 460, 461 & 463), #2 is a 2000 G500 Posts: 151 | Re: New brakes I love mine. They are on a 7,000lb plus camper and significantly enhanced the performance in several ways. You'll love them in every way. You won't see an RPM reduction if you go with true 35's. My KO2's are 34 1/2" and I saw a couple hundred rpm increase at my top speed. Make sure you adapt the rest of your brake system to be a disc/disc. That includes a new master cylinder (same as on a G500 or a 290gdT) and I believe you take out the check valve on the line going to the rear brakes. You'll also need longer brake lines. Don't over tighten the small banjo fittings that lead to the remote portal reservoirs. Also, pay close attention to the "clocking" of the rear portal box when you are setting up the rear axle and getting ready to weld on the rear flanges . At this point it is best to have the jack stands supporting the rear axle so the axle/body orientation is in its correct orientation during this clocking set up. Ask Wolfgang for directions/tips on this. GFG won't be much help. Enjoy! | ||

We spent some time on that but seem to have it right now. You are dead right on GfG. Such lousy response and lack of support! I'll look into the brake system and see if it needs any modification as you suggested. Thanks | ||
