Hawk Performance offers new compound for E30s!

#1

Hey guys,

Just thought I’d let you know the Hawk Performance has increased what they have on offer for e30s. I know many of you have tried the DTC-60s on the front, but up to now the HT-10 has been the most aggressive compound for the rear. Late last year I asked if we could get some better pads for the rear, so we tested the DTC-60 and DTC-70 at VIR in February.

60s all around did quite well and had very consistent temperatures front-rear, but I really liked having the 70s in the back to overcome the stock brake bias imbalance. It was very stable throughout both races with 60 front/70 rear.

Check with Andrew Racing to order yours!

Thanks, Mike. I’ll check on Skeen.com to see when your next event is going to be.

Your fan club in the SE,

Done. Called Jay earlier today. I’m excited for the new compound.

#4

Likewise, I had just ordered another set of DTC60/HT10’s from Jay and was able to swap to the DTC70 rear pads. Looking forward to trying them out.

#5

Where are you finding DTC 70 s for rear? I only see them available for E30 M3.

#6

325 and M3 use the same rear pad. CB

#7

Nope… M3 rears are different. I have recently replaced pads on my M3 and race car.

#8

Have had both in my hands at the same time. Rear calipers are the same also. CB

#9

I’m 1100 miles from mine, but remember the rears being longer on the M3. The pad manfacturers have different part numbers for them…

#10

Understood…the M pad is automatically more expensive! CB

#11

According to Hawk’s P/N, 325 use a 399 backing plate and M3 uses a 227. Maybe they are almost identical? Never seen pads off a M3.

You need a HB399U.630 for DTC70 rear. Hawk P/N are pretty informative. 399 it the backing plate shape, U stands for the material compound, and .630 is how thick the pad is new including the backing plate in inches.

Give Jay Andrew a call at Andrew Racing. I don’t think they are listed for retail yet, but he is 10 minutes from the Hawk plant and has them. Also, I know Anthony Magagnoli has some sets to sell.

#12

Some how I expected this response… By the way, I do hope you are right because I have a few M3 spares that will otherwise go unused, but remain skeptical…

#13

Jlevie mentioned possible “ice brake” conditions when mixing pads like this with ABS, any experience? I should probably just pull my ABS, but I haven’t yet haha

#14

There’s a number of very old threads re. my experiments with brake pads. As long as your bias valve spring isn’t some sad tired thing, don’t worry about putting too much pad in the rear.

During my various tests I tried to find a pad combo that would cause my rear to lock up first but I couldn’t do it. That included the highest bite pads that money could buy at that time. I’d guesstimate that the DTC70 has about the same amount of brake torque, or maybe a little less.

The only way you can find out about relative brake torque between different manuf’s pads is to test them against each other. What I did is put one pad at LF and the other pad at RF. If I went off and hit a tree at track left, the LF pad had more bite. And vice versa.

Without exception the only time I’ve been able to create rear ABS induced “ice response” is by braking while bounding over gaters. Road Atl turn 2 has got me a couple times this way.

There’s some deep ruts in the grass at the exit of RA turn 3. Try to avoid them.

Sean, before you remove your abs, you should read the SE30 rules. Remember, if it does not say you can do it, then you can not.

You can’t remove your ABS, but it might be ok to disable it. If there is a requirement that your ABS functions, I’ve not seen it.

After you ruin a few $160 tires, you’ll put your ABS relay back in place tho.

#17

I actually like the ABS, it seems to work pretty well. Don’t see anything in the rules RE: ABS either way.

#18

Without the abs the brakes will lock up one front wheel before any other. I don’t think there are many of us, or any, that can get more out of the brakes with the abs disabled. Ranger also made a great point. Guys seem to change there mind on the abs when they have to pay for a few flat spotted tires.

As for the rules, as I stated, if the rules don’t say anything about it, you can not change it. Section 1.3 This applies to everything on the car.

#19

Four wheel speed sensors = 500. Four RA1s = 600. Your right I will definitely need to flat spot a few before I change my mind.

#20

At Rockauto, front wheel speed sensors are $33.79 and rears are $57.99. That’s $183.56 for all four, or in terms of tires, right around 1.23 Toyo RA-1’s.
