Top arm, at the mo its angled up just over horizontal.

This picture shows where a normal mini suspension would be, you can see already the top arms are at an angle, you can drop another inch lower from here easily

OMG, R1mini, I want to kiss you! Is that a scale drawing? Have you got any other drawings like that, particularly showing measurements for the suspension system, and the hub?

[ed4ran]

Thats what mines like at the moment.

[R1mini]

Jammy there is no need, I'm sure about that. They are not my drawings I just found them on the web have a look here for more

I have a picture of the front suspension on R1minimagics car on my other computer I will post it tonight, you can see the top arms are heavily angled, but Dale reported the front end to the best bit of the suspension, only wanted to change it because he wanted to lose more weight and lower it even further

I have a 10mm gap between the end of the thrads on the shock and the bottom of the spring seat and my bottom arm is already horizontal so any suspension movement will result in a giving me a reduction in negative camber angle.

As your lowered suspension compresses you will get an increase in negative camber

Quite true David in most normal installations but at rest the arm is horizontal (and not pointing down to the ground as in the sketch above you posted) and at its longest point so giving the most camber, as the hub end of the bottom arm raises under breaking etc pivoting on the rose joint in the subframe so the distance from the car shortens and removes any negative camber by pulling the bottom of the hub inwards. Its easy to check, just remove the spring from the shocker and then work the suspension with the car in the air and with a camber guuge fitted to the wheel mounting face.

Ade, you have 180lb springs on the tubular front end???


Mine had 160lbs on the front (mini subframe) and 400lbs currently with the tubular z cars.

However, your spring/dampers are mounted differently so maybe very similar rates to the normal subby. With angled springs (like mine) you need much higher poundage.

Cooling query folks: I have never worked on anything apart from mini's so the R1 cooling has me in a bit of a tizz even though I have the ZCars DVD. Anyone mind telling me how wrong my attached diagram is? and even better, correcting it for me?

Will get your brains working anyway

- I have helpfully marked some other bits I am very not sure about in the section titled "other bits"

thanks for the help
phil.

The drivers side looks right. The only bit I think you've got wrong on the passenger side is the tiny pipe hidden in bottom of engine next to large intake pipe. This goes up to idle up valve(choke unit ) located on back of throttle bodies. The other pipe from this valve(choke unit) goes into a small pipe located in the head hidden under the throttle bodies. I have listed out my setup below if this helps.


bottom rad hose to large pipe located under sprocket
small hose from this point goes up to the idle solenoid on the throttle bodies
other side of idle solenoid goes to pipe coming out of the head underneath throttle bodies
top rad hose to thermostat housing
alloy 4 way connector piece supplied by z-cars fits into this pipe just before thermostat housing
one pipe from 4 way connector goes to bottom of expansion tank
other pipe from 4 way connector goes to oil cooler
small pipe from thermostat housing goes to top of expansion tank

Mines a 2004 engine but should be the same

Fab Pete! thanks mate - I have got more correct than I thought! Your above also explains where my two "other bits" fit in - hurrah! thanks a lot.

Hi all,

Does anyone know where I can get filter foam for an air filter, that I can just stuff into my own filter casing, rather than buying a ready made filter, surely I must be able to get something similar to pipercross foam in sections and fit it to my requirements or something like that ?

thanks
phil.
