Default Brake Bias

I previously had a MY04 with oem discs and ds2500 pads, I loved the set up for my use so I have just done the same to my MY08.

I took my MY08 car for a drive today and it feels like the front dives a lot more than my MY04 did, but I may be wrong.

So the obvious question did the brake bias change between the years? I have a track day booked and the brakes feel great but just seemed the front dives more.

Honda suspension has been thru several variations. There are details (somewhere) here but I've not paid much attention. Your '08 front suspension may have softer or revised geometry from your '04.

Ive seen the suspension thread before and that says the MY08 front is stiffer on spring rate and arb, rear springs rate is stiffer and the arb is the same. On normal driving the car is fine and the rear doesn't dip as low when compressed, my mate followed me on the same road and commented the MY04 was alot softer.

So those figures don't match the feel of the car when braking, which brings me to the brake bias question

Was your first really a MY04? Supposedly the original design of the geometry of the suspension was in part to stop the car diving so much under braking, but that also lead to the slightly twitchy nature of the car. For 04 in addition to softening the springs they changed the wishbones to make it less twitchy, but also meant the car would dive more.

I certainly would not say my MY04 dives under heavy braking, more like the car squats.

so it does sound like its the set up of your MY08 that's questionable does it definitely have stock dampers and springs ?

what front tyres did you and have you got?

different sidewalls could alter the feel

Are the rears functioning at 100% ? Mine feels like it's diving a bit more than it used to and I'm planning a rear calliper refurb as a result.

Is it an MY08 car with the stiffer set up, or a late reg'd MY07 on an 08 plate? If it's an MY07, it's got the softest set up of all the variations......

Not on the front it doesn't (according to the link above).

Both the 99 and 02 variants have softer front springs than the '04 and '07 (and the 08 are even stiffer).

In general, the trend has been to softer rear springs and stiffer front springs.

Of course, the compression characteristics of the dampers are unknown, and those will have a significant effect, too.
