plus you'll lose in the wallet too, I like the torx head they don't strip out as easily as hexes especially if you use locktite
If you strip the hexes on Ti screws, you are either using the wrong size allen wrench or you just should be allowed around any kind of screws at all.

On your cars, does your diff pulley "wiggle" between the diff halves? Mine does (I've used many pulleys) and I'm wondering if it's normal, or if I've done something wrong. The diffs seem to work okay, but it does seem like the wiggle affects the action of the diff a little bit.

Hey guys,

What effects does lowering or raising the diffs? I have looked everywhere (including the Xray tuning guide online) and can't seem to find any info.

Thanks

isnt that for loosning and making the belt tighter?

On the RDX, you can move the diffs up and down. They don't appear to be there for belt tension. I was thinking they would be there for more roll center adjustment....

I'm guessing it has more to do with the height that the torque is applied to the wheel. Take for example a higher rear diff in realtion to CG height, under acceleration you would see less of a tendancy to raise the front of the car, but under breaking it would have more leverage to pitch the nose down. Just my thoughts, not sure if these are the most dominant physics that this change will see.

Lowering or raising the diffs is not to effect belt tension. The raising and lowering of the layshaft and the front belt tensioner are the 2 ways corally means you to adjust the tension of the belts.

like many here, i am not sure on the physics of raising or lowering the ddiff but from personal experimentation and experience from others:
-Raising the diff offers less traction at that end
-Lowering the diff offers more traction at that end

Hope this helps!

Straight from XRAY site regarding Diff height. Now, not 100% sure if this would translate to the RDX, but I would imagine it'll be close. Keep in mind XRAY can only raise or lower the rear diff.

The height of the diff influences the amount of weight that is transferred during deceleration (rear to front) and acceleration (front to rear). When the rear diff is in the high position the torque applied to the diff works on the car at a greater height too. As a result more weight will be transferred between front and rear.

The different settings have the following effects:

- High diff = generally more steering

- Low diff = less steering, more stable

- Middle diff = steering and stability in between High and Low

This setting is best used after you've already achieved a good base setup to fine tune steering and stability.

Hi Guys

I'm about to get a new car, and the RDX is very tempting. Basically I want to know which version of the car would be best for me;

I'm from the UK, and normally race Foams on carpet (not as high traction as you have in the US) as well as outdoors with rubber. I realise to get one car for all conditions will be a bit of a compromise, what do you suggest?

Thanks
Oli

Honestly, I think the Dual diff Uk edition would be perfect. It seems to be the most versitile kit of the 3 different versions. Since front one ways are really scary to drive with on foams, and a diff can still work pretty well in most condiditons on asphalt and carpet.

So Jeff,

What did you end up running at the recent state race?
