Got a track related question? I'll try to answer.

What pads would you recommend for the rears? Rr racing b20 up front, assume stock rotors in back. Stock power on kw v3.

What's at the rear?

BP-20 F and R

Sounds like the RR kit actually is not balanced at all...

Front vs. rear...

Maybe time to go back to Winmax or try Carbotech haha. These came with the kit though.

Wait what? Same pads front and rear?

Are you noticing significant rotation in the car or the rear getting squirrely under hard braking? That seems like a LOT of rear bias.

Yes, I have the stage iv front and stage i rear kit. So I get to use the same size pads front and rear. It is actually very nice. When I get pads I like, if the fronts still wear fast I just put the rear pads up front and buy new rears.

The brakes do feel very well balanced. I admittedly don't have a ton of experience with a ton of different braking systems, but I have enough seat time in this car to know. I can also attest to the fact that this kit (as well as the AP kits) is so much better at heat management and is well worth the cost in the long run.

Can you take a picture of the pistons for me when you take the pads out? Same angle of each caliper if possible.

Yeah, it might be a while though.

This is what my P.mu CR pads look like after one track day. Sorry bout the poor pictures:

I've got a question around spring rates (apologies if it has been asked before).

The stock rates are something like 2.3KG front and 3.3KG rear, making the rear about 50% stiffer than the front.

It seems most aftermarket coilovers are running the same rate front and rear, or very similar rates. eg. 6kg/6kg, 8kg/9kg, 8kg/7kg. Its certainly not 50% heavier on the rears like the stocks.

Doesn't this change the balance of the car towards much more understeer?

Or are you gaining a lot more front grip with the coilovers via the other improvements (greater camber etc) and negating this?

I've read a lot of people complain that the BP20s don't last and seem to wear faster the farther you get into them. I'm planning to get the RR Racing sport front kit but I don't plan to run BP20 pads.

RR Racing claims stock bias is retained with the front kit but recommends running their rear kit to move bias to the rear vs OEM. I don't plan to get the rear kit so with that in mind, it looks like I may want to consider running a more aggressive pad in the rear? I was thinking of trying something like Carbotech XP8 in the front and XP10 in the rear, would this be advised or should I use similar compound front and rear? Note that I don't have any aero at all, not even a spoiler.

Suspension works as a system between dampers, springs, tires, inflation, valving, settings, bump stops, roll bars, bushings, etc. You cannot just look at the spring rate of one setup and compare it directly to a completely different setup. You should look at the total product. Please, correct me if I'm wrong.
