Hi

$8 for 1 coupling? , and you need 8, thats a bit pricey...

Also it states in the book that you can change internal ratios of the car, and that 1 ratio is best for stock, yet it does not state which one...
Also in the assassin book it states that the single belt design is best for stock, why wasn't this design covered over to the new rdx and phi ?, why was it change to the 2 belt only ?

Thanks Ya`All

On the PHI, you do not need the low roll center blocks (79121) as the way the PHI is designed with the standard blocks (79120) down is the same as the RDX with the low roll centers down. Atleast that is what I remember being told.

I have an 88 spur and could put a 58 pinion 64pitch. It's the largest pinion I have. You'll have to remove the pinion just to tighten the motor. I hope there will be no reason to go there

If that is the case, then why in the phi manual does it list the 79121 as a tuning option for the phi for low roll center ?

I would have thought the same thing. After talking to guys at CorallyUSA, the plastic nuts are fine, just use a small amount of lock-tight on the diff nut. I've had my diffs apart 10 times (at least) and I'm still using the same diff nuts.

No one makes a diff nut in that size. It is too short and no options available. It is a custom part as far as I know. If you are having problems, then something is not set right. Some of the early kits didn't have the coned washer included to lock them down. The local distributor and/or hobby shop should have been able to obtain them for you.

Only when used improperly.

I think this is in part to the original design of the PHI. I do not believe it was originally to have such low roll centers out of the box. The optional holders will work, just in the up position which will really raise the roll center.

I think the change was made due to the fact that people did not want to purchase 8 individual roll centers to make it lower. So the stock option is to run the lowest roll centers and shim higher as needed.

It depends who you talk with honestly. I have run the 2.0 ratio in the RDX of course the whole time. I ran the 1.7 ratio at the Reedy Race. I plan to use the 2.47 ratio at the ROAR Nationals next week. Hopefully I will know more from this all.

Some will say that the higher the ratio........ 2.47........ will give you more acceleration. Hopefully I can respond better to this later on.

Hi All

Why is the top deck on the phi tight? , even a few mates of mine their phi top decks are tight, you have to use a bit of force to get them in place, surely it tweeks the car?.
