Yeh the delrin is fantastic i use it i found the standar alloy ones to be a little weak on a small track never had a problem with the delrin one, Also it should be a little lighter

Hi Guys need your help,

I am in the process of putting TRF shocks on my PHI, are there any tips or mods needed to do on the shock before putting them on or are they a standard fit?

Thanks

i use the 1mm down type alloy retainers on my trf shocks with the tamiya eyelets and the aftermarket blue alloy ball mounts and spacers all round :D
and it looks sweet!!!!!!!!:nod:

Hey hey.
I got some Diff Question for ya all,

Do you use the corally diff grease, seems to tacky/sticky to me ?
Is it important to use those two O rings on the diff out drives ?
And whats the trick to keep the diff's tight, mine will not keep there tension .

Thanks

Kevin

Read the instructions on diff building. I use the Coraly diff grease, its good stuff. Use the O rings it keeps the diff oil from coming out and cr@p from going in. It says in the instructions do not over tighten or it can damage your diff parts. It also says in the instructions if your diff comes loose to use some thread lock.

Take Care,
Cheers, Patrick

Hey yes i use the corally white grease it is fine, also when rebuilding diff always apply a small amount of thread lock to the outdrive threads and when i put the diff in the car i start off a lil loose to run in as i have noticed it gets tighter as it spits the grease out, and then tighten to your liking.

set up advice
 
Hi Guys,

Recently got my Phi, it's nice but am having some issues with oversteer :confused: ... mainly on throttle and corner exit.

Have tried changes in the following order:
- harder front springs 19pound (17 on rear)
- lengthen rear camber links
- lay rear shocks down one position from kit.
- Introduced kick up at front (turned front couplers over)
- Higher roll centre on the front using couplers ('dots' up all front couplers)
- Thought I may have had to much 'all round grip' so changed to hardest
springs (front 24 & rear 22).

I have no sway bars, ride hieght 5.5 all round, used xenon 36 tyres (hot day).

I seemed to gain some improvement from increasing front roll centre change, however overall problem still there :weird:.

With all set up changes, the oversteer problem became worse after a few minutes into the run.

Would appreciate any advice you may have guys.

Cheers

If it gets worse during the run, your tyres may be overheating. Im not terribly familiar with the Xenon tyres, but would suggest you try a Sorex or Much More tyre to compare. If its still doing it, at least you know it isnt tyres.

To get a bit more rear grip you could also try more rear toe in.

What hole position on the rear hub are you using?

You should try sway bars it will settle the car down alot, also from what ive heard the xenons have alot of steering prolly to much taking away rear grip, that could be ya problem most likely

mazmo 02-24-2008 04:19 AM

Thanks for that, have heard that about the Xenon tyres too ... although I did try Much More 32 Friday night and had similar issues but not as bad.

Agree the sway bars are the way to go .... they made a huge difference on my HB cyclone as well.

hey guys just wondering if the phi rear diff fits the rdx ?
cheers

mazmo 02-24-2008 04:31 AM

Thanks ... experienced similar problems with Much More 32 on Friday night, but not as bad. So I guess not a tyre issue.

I am using the middle hole on the rear hub (and lower inside hole on the shock tower - as per kit)..... which are you using ?

More rear toe :) I should have thought of that ...will help.

How to Blueprint your RDX, check out this link http://www.corallyusa.com/2005/blueprint.htm

Its old but it has some great reading on diffs and shocks.

ZMANN i do know the old RDX diff fits the PHI so i cant see any reason why the new diff wouldnt fit the old car.

MAZMO The PHI was designed to have a LOT of steering, this is probably the one main reason it has been so dominant, this may not always be to everyones liking. Sway bars do help alot with settling the car down. You may also want to try a shorter front link.

Thanks Ari ... yes the PHI certainly has much more steering than I am used to, alot better than not having enough :)

Will add the sway bars. In the interim will shorten the front link .... am also considering adding more rear toe in. Do you have any other suggestions ?

Thanks

Alan

Also try lengthening the rear link will give u more grip in rear, so less steering
