Editing Brake pads (section)

[http://www.hawkperformance.com Hawk Manufacturer Website]<br>
According to their catalogue they only produce Lotus brake pads/discs for Elise 2001-2011 and Exige 2010-2011 (need more info: is this pad compatible with more years?)<BR>'''User information required'''<br>
Code reference:<BR>
*HB180?.560 Front brake pads
*HB278?.465 Rear brake pads
Instead of ? fill in compound code: 
'''B'''=HPS 5.0, '''E'''=Blue 9012, '''F'''=HPS, '''G'''=DTC-60, '''N'''=HP Plus, '''R'''=High Performance street/Race, '''S'''=HT-10, '''U'''=DTC-70, '''W'''=DTC-30, '''Z'''=Ceramic Brake	
<br><br>
note: digging through all documentation I found values  inconsistent. Even if °F or °C was noted, it wildly varied. Example: HPS 100-1200°F (converted: 37.8-648.9°C) operating temperatures in one pdf and in other was 100-500° (not mentioned if it was °F or °C - I don't make assumptions when it comes to safety). I used this document and this one has different values of same brake pads in same document: http://www.hawkperformance.com/sites/default/files/downloads/HAWKBRAKEGUIDE_FINAL_2.pdf<br>

=== HPS 5.0 ===
Compound code B; 100-1200°F operating temperatures

=== Blue 9012 ===
Compound code E; 250-1000°

=== Blue 42 ===
Medium torque pad developed specifically for road, rally and circle track racing<br>
This medium torque pad was developed as the next generation of the legendary Blue 9012 from Hawk<br>
Wide operating range from 100° to 1000° F—optimal range of 250° to 700° F<br>


=== HPS ===
HPS Ferro-Compound<br>
(comment on other non-lotus forum)<br>
On the street don't work well from cold.<br>
They were so bad in 40-50 degree weather when new that I could hardly prevent the car from creeping forward just from the engine idling with the automatic transmission in Drive. And the first couple of brake applications were scary also. Almost no stopping force, like the brakes were wet. They did get noticeably better after they broke in, but they never inspired confidence on the street. It was hard to get the ABS to engage, and in testing hard/panic stops it always felt like the first maybe 40 feet weren't slowing you down much, just warming up the pads. You could feel the change in braking force while slowing down just from the pads warming up. And then after 1 or 2 hard brake applications they got a bit grabby. <br>
Compound code F: 100-700°F operating temp



=== HP Plus ===
Key Features:<br>
Extremely High Friction Output<br>
Fade Resistant<br>
Worthy for Autocross & Club Racing Events<br>
Warning! Due to the dramatic friction levels produced by this product to achieve “race-level” braking, rotor wear, noise, dust, and pad life may be affected.<br>
Compound code N: 100-800°

=== Street/Race ===
Compound code R: 100-1200°F operating temp<br>

=== HT-10 ===
HT-10 pads are intended for '''track use only'''. If you try to use them on the street they’ll be far below their operating temperature range and will eat your rotors and make a lot of noise.<br>
Compound code S: 300-1300° ; race pad

=== DTC-60===
Compound code G: 400-1600° ; DTC Series pads intended for '''track use only'''—not recommended for street use

=== DTC-70 ===
Compound code U: 400-1600° ; DTC Series pads intended for '''track use only'''—not recommended for street use

=== DTC-30 ===
Compound code W: 100-1200° ; DTC Series pads intended for '''track use only'''—not recommended for street use

=== Ceramic Brake ===
Excellent stopping power in an ultra-low dust, low noise ceramic compound! '''Not intended for track use.'''<br>
Hawk Performance has introduced a premium, high performance, ultra-low dust, low noise compound called Performance Ceramic.<br>
Performance Ceramic is engineered to reduce brake NVH (Noise, Vibration and Harshness), creating a quieter performing brake pad. Furthermore, the ceramic brake pad formula has a linear friction profile that allows your ABS brake system to work more effectively. With Performance Ceramic you can expect reduced brake pad wear, lower dust output levels and a rotor-friendly brake pad.<br>
Performance Ceramic – quiet, clean & fast stopping!<br>
Compound code Z: 100-650°<br>
