Yeah, good idea

Hi MSB.

I have found that the RDX needs some extra weight on the battery side of the chassis. This is because the batteries have been moved inward and the motor has been moved out slightly on the other side. The standard car is quite underweight though which compensates for the balancing weight required. I'd suggest putting four 8-gram weights in the back right corner behind the battery, and then evenly spread any other weight to get your car to the legal limit.

Aaron, by 'ultra lows' do you mean the custom lowered shock towers that people have been making? Sorry, I haven't kept up with the other RDX thread. What handling characteristics have you found with this modification?

Pat.

Default Ultra low

Pat,

I believe he means ultra low roll center mounts for the arms.



Aaron would you please pm me your rubber set up. I have not found one yet myself, but I will get it sooner or later. Are you running mod or stock or 19t.

Thanks,
Steve

Why take up server space for a double thread? I would just use the one that's already there.

Default Rear Toe adjustments ????

Anyone knows if there is a handling difference in using toe spacer compared to using -2 degree rear blocks?

Another one is: What the best way to lower the spring retainers up in front. Is there an option or should I just shorten the lower ball cup for the retainers to sit lower?

Well generally when you use the stock 0 deg carriers you have to use shims to get the toe in. Since it sweeps the arms forward you are shortening the rear wheelbase. This will give you a little more initial steering, but will put more weight over the rear tires. If you use the 2 deg carriers, you wotn nee shims. There wont be any arm sweep, and wheelbase will bit a bit longer. This puts a little bit less weight over the rear tires so it might give a touch mroe on power steering. The pins are also parallel to the centerline of the chassis, and that is when the suspension is most efficient. So there is a combination of things that it could do. I'm not totally sure since I have not tried it yet.

Seemes like a lot of you talk about lowering the shock tower up front, but does it really help or is it just cosmetic and if it is better for handling, could it be donr somewhere else onthe car to get the same results? The other post about it seems like it was mostly cosmetic.

Lowering the shock tower enables your to just lower the body. I guess it can give you a little more steering since your body is a bit lower, but it does look cool when you can slam a sedan body down
