Hi,

I thinks it's a good idea to start a thread dedicated to tip, tricks and mods for the B4 and B4.1

Here are some thing I'v don't to my B4.1 to make maintenance easier:

I changed the screws to the bigger ones, I'v stripped several of the standard ones..


Also changed these so it's easier to loosen the bleu aluminum shock mounts.


After the first races I ran, I managed to strip the standard screws so I changed them out for bigger ones


I found these cva boots on ebay. I think they are still selling these.
I bought the B44.1 ones, you get 3 pair and pay less then if you would buy 3x B4.1 cva boots..
(This only fit's the B4.1..)


And I recently done this mod to the wing.

I had these spare wingmounts that I bought 2-3 years when I ran a B4.
Since I don't break them, I done a little mod :)

Cut the little thing were the clip goes off.


Make the mount flat, I'v done this with a knife, you could use a file also.


Take you bodyreamer or a drill and make a hole where the screw will go.
Make new threads with the screw.


If you do this also with the other mount you'll get something like this:
Use a little shim or a countersunk washer to make it look even better!


I hope you likes my little tricks/mods :D

Don't forget to add yours too!

When I was racing a B4 AND the GT2 came out these were the up dates that I did, so most of these are for the B4, don't know how many of these are parts at are used on a B4.1.

6276 GT2 ballstud .200
6277 GT2 ballstud .300
7921 GT2 Steering Arms
(to use these you will need to remove some material [where the axle come out at the wheel bearing] from the steering arm to work)
7919 GT2 Front Caster Blocks (25 degree)
7922 GT2 Front Caster Blocks (30 degree)
9730 B44 rear hub
7935 3/16x1/2 bearing
7933 bearing crush tube
7889 5/64 x 1/4 Bearing in place of Steering Rack Bushings
3858 Black Ball Ends on Steering Rack

Why would you want to change the ballstuds?

Yes, the B44 is also a great upgrade

Front axle tip! Works on any AE that has e-clips holding axles to steering arm. AND any racer that has any time racing with a e-cliped anything knows this. :biggrin:

Shoe Goo the E-clip on the end of the axle. Reason, axles develop (end to end) a bit of play in the steering arm axle socket.

The "original" ball studs are softer.

The "original" steering ball studs have a taller profile which makes "Bump out" adjustments harder to make.

You difference them by the color or by the hex hole in the ball?
The top has a inside hex (good) the bottom has a outside hex (bad)

Well I never broke a ball stud so it can't be that soft :D
Most are broke at the rear link mount. Have had them break on a T4 shock tower link mount.

Never had that.. And when I had my first B4 (a RS) I ran on gravel, made huge jumps all the bad stuff :p
Never broke a ball stud and the car also had the 'bad' once like you just explained :)

Found the info about the steering ball studs.

===

Why black ballstuds are being used on the steering rack in a lot of the new set-up.

The black ballstud is shorter so it lowers the inner pivot for less bump steer.

Some people run the Avid steering rank that hasn't got a servosaver.
If you want also a non-servosaver steering rank, just glue the 2 parts together.

Another one ;)

Put a washer on the screw that secures the shock on the rear A-arms.
Prevents the ball end form popping off.

With those CVD boots - you can also use shrink wrap. Save a few bucks does the save job.

Guess it depends on the shrink wrap, mine was still pretty flexible. There are so many little tricks with these cars.
