Not sure if you consider it a suspension geometry adjustment, but I have found that having the right droop, both amount at each end as well as balance from front to rear, is absolutely vital with this car. Not sure anything else has made as large of a difference in my testing.

Going from the 6.4 rear block to the 5.7 rear block also makes a huge difference in car feel.

'what is the single suspension geometry adjustment you found to have the biggest effect on the car's balance, guys?'

I would say there isn't one single suspension adjustment that has the biggest effect on a cars balance. I think starting with your shock package is the most important aspect to any cars balance. Once you got that down you can then focus and fine tune the cars suspension geometry.

When it comes down to it, each geometry setting has it's primary and secondary effect on a cars overall balance (Entry, Mid, Exit).

For me its getting the diff where it needs to be, over all setup doesn't change much, might go up a spring rate or a little extra rear tow, but If i can get good rotation and drive out of corner that's where you make up the most time.

Other than that constantly checking and making sure the ride height hasn't changed due to tyre wear after a run.

Yukijiro Umino aka Volkers mechanic said the there are no difference between left and right side...he said both are the same. Just asked him today on Facebook message. I believe the dot is from the molding process.

Nice. I just took my car apart and flipped them because everyone said the dot has to go forward

the manual does say : pay attention to the direction of the part

not sure why the tekst is there, if it was for the dot it is not very clear.
if it isn't about the dot, i can't see what other part it could apply to

Been watching the topic about the rear hubs, little dots and the toe direction and I do think that some people are "SERIOUSLY" over thinking the instructions.

So before I go to explain I want people to clear their thoughts about the build, marking on the parts and any other information that was injected into the topic over the past few days.

Done?... Good.

Now look at the picture below that was posted up a few weeks ago and just answer the question that is posted just after...



Could the "Pay attention to direction of part" be in regards to the arm so that you don't accidental assemble two left hand, or right hand arm assembly?

no because the arm has his own pay attention box, there is a 2nd box pointing at the hub

Exactly!!! There are Two ways to get this assembly wrong.

The Arms and the Hubs are interchangeable meaning that if you flip either one of the parts, not swap parts, you will end up with the opposite arm assembly.

You know I'm making sense here.

that does make sense

maybe we did just freak out because of the little marks on the hubs

but didn't someone measure a difference?

That could be because of many different reasons. Tweak being one of them and how many shims he had between the suspensions shafts. The bearings may be slightly misaligned thus altering the shaft angle and the hex nuts do clamp onto a pin that can twist if the nut centre hole is a little large. I know when I measure Toe angle on the front I turn my steering one way and measure; turn it the other way and measure; and then lift the front and place it down in neutral and measure, all because of the slop that can be present within a car.

Some of you guys seriously went overboard with the rear hub.

Haven't the rear hubs been the same since the BD5?

Default Screw in layshaft

Hi all,

My names Josh,

I wonder if someone can help, sorry if this has been asked previously,

When I first assembled my BD7 15, I couldn't tighten the little M3x6 flat head screw that goes into the layshaft, if i do, when the drivetrain runs forward the whole drivetrain locks up, as the car was new i didnt want to over tighten it, so i decided to slacken it up (maybe a little to much) on the first run with the car, the screw and bearing flew out during a race and I lost them.

Is there anything i can do to prevent this?

I have brought new screws and the washer and bearing that I lost and put a little thread lock on a M3x6 flat head screw, this has so far worked for 5 rounds.

Ive heard I can use a button head screw without the washer, but im unsure what size screw, maybe M3x8 Button head?

Just wondered if anybody has/had this problem and what you have done to prevent it, also wondered what you lot are running.

I have attached a pic of the screw in question, the pic shows someone using a button head screw with no washer, hence the question.

Any replies and help is appreciated.
