I bought these rotors to replace my stock rotors. They were fine for the first 3000 miles but after that I started to notice a brake shimmy when I applied the brakes. It has gotten so bad that when I brake the steering wheel vibrates really bad. I called tire rack and they told me to get the measurements to the rotors at a garage. The garage took the measurements and the rotors are bad already. I would not recommend these rotors to anyone. The stock rotors on my evo were better

July 13, 2009

I''ve been tracking my car for a few years always using plain rotors. Then, for some rediculous reason, I decided to try slotted rotors. First I tried Stoptech; they lasted me for a few track days, but not as many as plain OEM rotor. At that time, what I should have done, is go back to the plain OEM rotor, but instead I purchased the DBA 4000 Series rotors hoping they would last longer then OEM or Stoptech rotors under track conditions.

After about 1,500 street miles (highway miles when driving to road courses) and about 400 miles on a race track one of the rotors cracked. The exact same thing happened to my brother on his Subaru WRX.

My brother and I will NOT be purchasing DBA rotors or any slotted rotors in the future. So far plain OEM rotors seem to work the best on the track.

When I first installed these rotors they were outstanding - they met all my expectations untill they warped after only 20,000 miles most of which are highway miles. They can not be trued due to the slots. The shimmy is very noticeable in the steering wheeel under braking - to the point that I get comments from people who ride with me in the car. They will be coming off the car very soon and placed in the scrap steel bin!

Excellent upgrade over the stock/oem brakes and pads. The combo is very consistent with excellent bite and has no fade during AutoX.

While I don t drive my Subaru competively, I want maximum braking performance for safety. I put DBA slotted rotors on Sube s front wheels. Smooth,vibration and fade free performance. I ve got PBR Axxis Ultimate (ceramic/kevlar)Pads on my Sube,, front and rear, and they re outstanding performers. These Pads do wear faster than other ceramic pads but they re still great.

But the DBA Slotted rotors are second to none.

The combination of Hawk performance ceramic pads and dba 4000 series rotors on my 2005 Subaru Legacy GT has overall been a great buy. Lower levels of dust than stock and much improved brake feel have exceeded my expectations. Only slight negative is the price..

purchased stainless G stop brake lines for 05 Mustang. Installition was easy and straight forward. No problems encountered took about 45 mins total (vehicle on rack). Immediately felt difference in stopping. Vehicle has DBA drilled and slotted rotors with Hawk HPS Pads and stock calipers. Stopping is awesome ten fold better than factory.

This is a really nice set-up for a street driven, or occasionally autoX d WRX. Noise is the same as stock, except when very slowly releasing the brake pedal, like when going down a hill, there is a slight shudder. Cold bite is excellent, even in sub-freezing temperatures. I did a really hard drive on a twisty back road, with lots of heavy braking and minimal cool down time between turns, and the pedal became slightly grabby near the end of the run, but pressure and performance stayed very consistent throughout. Overall, I am extremely happy with this setup and will replace these pads with the same again when the time comes.

Five HPDE weekend events and not one hairline crack on my OEM Z51 drilled rotors. Two HPDE weekend events on DBA 4000 s and they are already peppered with hairline fractures :-( What s worse? I called TireRack. They asked for pics. I sent them. The response, the manufacturer believes the cracks are caused by "Overheating" and hence NOT covered under wrranty. Hmmm... I checked those color heat indicators immediately after I came off the track and NEVER did the "Red" one turn white. Go figure. Though I was on the track, I never pushed the car more than 75%. IMHO ditch DBA, get the el-cheapo OEM rotors - they last a lot longer and cost a lot less.

I SHOULD HAVE TAKEN THE OTHER NEGATIVE REVIEWS MORE SERIOUSLY. PLEASE TAKE MY ADVISE TO HEART. IT WILL SAVE YOU A LOT OF MONEY AND TROUBLE.
