when it comes to brake pads, what is everyone using? the OE pads are decent on my 18wrx but lacks a bit of the bite that i'm used to previous car 11wrx with hawk hp+.

as much i despised the hp+ noise especially on light braking, they were pretty good for autox and able to brake harder in later areas of the autox course.

i'd love to get some ferrodo 2500s pads for my 18.

what's the consensus for other regular autox?

plans for this year
- bridgestone re71's
- proper alignment
- brake pads

that's it..... getting to be old timer at autox..... nearing 20 years attending autox events.

i was going to get ferodo ds2500s but they are fairly expensive and my stoptech sports are enough to lock up the tires anyway

Since the conversation has moved to brake pads, I figured I'd put in another plug for my Carbotech AX-6 pads. No reasonable offer refused; just looking to get them out of my garage and help out a fellow autocrosser.

EDIT: SOLD!!

How would you guys go about creating a little more rotation mid corner and on exit on a fully built autocross WRX?

I just feel like I'm leaving so much on the table when it comes to steady state cornering, as well as exiting corners. I know the goal is to brake as late as possible, rotate and aim straight out, but if I go too hot into a corner, I push pretty hard on the RE-71's. If I'm 10% more gentle, it turns in quite well, but it looks like from my videos the only fast areas are when the turns are point and shoot. Also as soon as I get on the throttle, the thing just goes straight, even with all that traction. Do you guys think this could be solely due to rebound adjustments on my coilovers, or is there something else any would try?

Please ignore the first cone on the track. Accelerated too hard on what was supposed to be a 44.xxx run, but that run was still by far my fastest everywhere else.

One of the excellent wrx drivers I know recommends up to 50psi in the rear to help rotation.

A number of drivers have high speed accelerometer recording/replay. This looks like the way to go as they can easily compare different approaches to a given turn.

Qstarz LT-6000S GPS Lap Timer is a great one If you are serious and want to improve your game on the track.

How do we keep the rear tires on the ground? Biggest front bar I can find ?

I would think it would help some, but with a trade off of less rotation and some push in tight elements. I try to mitigate wheel lift with a quick stab of steering wheel input to set it back down. Mind you I run a rear bar full stiff, but have thought about setting it on the middle setting to reduce the tail happy handling on my car.

We campaigned a 2016 WRX with Performance Pack Nationally last season and ran the Eibach front bar on the low setting IIRC. Co driver and I won a couple of tires at a few National Events (Bristol, Pittsburgh, Toledo) in DS but got crushed in Lincoln (15th and 16th). The other fast guys were running rear bars which I think worked better in Lincoln but we had some other issues that cost us time too.

The front bar will make it slalom/transition like a champ but you'll notice some push in sweepers and tighter elements.

I agree wholly, with the rear bar my car feels vague in slaloms. On a side note, can I ask what tire brand and the psi you used? My re71 are wearing down the center ribs more then the outside edge. I have been running 33f/31r and swapping front to rear between events. Any input appreciated!

We ran BFG Rival S 1.5 in a 245/40/18 on the 8.5" wheels that came on the Premium 2016's. Target hot pressure was 34F and 36R. We also put STI dampers on the car.

Do you get much rollover on the front or rear tires with those pressures? I've been running Direzza ZII's in the same size as your tires with 40F and 42R. I get roll over on the front tires to just past the tip of the triangles and no rollover on the rear at all. The car seems fairly well balanced at those pressures, but I wouldn't mind a little more traction all around. My car is a 2016 premium and it is completely stock.

I don't have any experience with the Z2's but I never ran pressures that high with RE71R or BFG on either the 15+ STI or 15+ WRX.

I'm not an engineer but here are my thoughts. In stock trim you are extremely camber limited in the front at -1.5max. The tire is going to roll no matter how much pressure you are going to put in it. Why not try to maximize that patch with less pressure?

Also the rear is just along for the ride. I'd experiment more with lowering the front. Maybe try to shoot for 35 hot and see how it goes and keep the rear around 40 hot?

Also get better tires...
