  • Introducing CSG Spec Brake Pads

    CSG Spec brake pads

    We are proud to announce the launch of CSG Spec brake pads to the general public!

    CSG Spec brake pads have been developed to meet the specific demands of customers in GT Racing, One Make Racing, Time Attack, etc. where off the shelf products were often inadequate.

    The result is a line of sprint & endurance friction materials which offer superior peak brake performance, pedal stability, braking control, higher fade resistance and lower wear.


    We have lots of sizes in stock, with many more applications available upon request:

    Toyota 86 & Subaru BRZ brake pads for standard calipers

  • How ACE headers are made

    ACE Header is considered the best exhaust manifold for the Toyota 86 / Subaru BRZ / Scion FR-S. Here's a quick look at the production process of the ACE headers at their factory in Taiwan:


    CSG has used ACE headers in their BRZ with great success, winning Super Lap Battle's Enthusiast RWD class two years in a row (2017, 2018) as well as SoCal's 86CUP Street & Modified classes. CSG has helped develop base engine maps for naturally aspirated and boosted applications  -both supercharged and turbocharged variants.


    The following is a dyno chart of a 2017 BRZ with:

    ACE Header on ACN91 gas (California 91 octane) : 18% HP gain
    ACE Header on E70 mix fuel: 25% HP gain

    The ACE Header boosts power across the whole RPM range, with even greater gains when paired to the ACE Front Pipe and a Flex Fuel (E85) kit. Our Power Package for 86 / BRZ includes ACE Header, Flex Fuel Kit, tune and more!

    Besides the ACE Header 350, there are several specialty models for left-hand and right-hand applications to choose from. If you are not sure which one you should get, just ask us!

  • List of Stock Cars Too Loud for Laguna Seca Sound & Noise Limits


    Monterey County's sound limit ordinance for Laguna Seca requires most track day events held there to adhere to a strict 90 dB sound limit.

    During the majority of track days held at Laguna Seca, cars whose noise levels are measured to be over the 90dB threshold get a mechanical flag for a sound violation. See the "donut" flag three times, and you're finished for the day. A popular workaround is lifting or coasting while approaching the sound booth, located between turns 5 and 6. However, it's not unusual for the staff to perform checks with a mobile mic unit from other turns.

    Many sports cars sold in the US market are already too loud for Laguna's sound limit in stock form.  For example, all of the following models in showroom trim are known to get flagged at Laguna Seca for being too loud:

    • Chevrolet Corvette Z06 (C6, C7), ZR1 (C6)
    • Porsche 911 GT3 (996, 997, 991.1, 991.2) / GT3 RS
    • Porsche Cayman S/Boxster S/GTS/GT4 (981, 987)
    • Dodge Viper
    • Ford Mustang GT350
    • Nissan GTR (R34)
    • Ferrari 458
    • Ferrari F430
    • Audi R8
    • Lamborghini Huracan

    Days with cloudy or foggy atmospheric conditions can make compliance with limits even harder, as sound bounces off the cloud layer.

    Making your modified Toyota 86 or Subaru BRZ pass Laguna Seca sound test

    While the Toyota 86 / Subaru BRZ / Scion FR-S are rather quiet from factory, just adding an aftermarket catback exhaust will typically increase sound levels beyond what's permitted at Laguna Seca.

    CSG has co-developed several exhaust solutions to keep output under a 90 dB threshold without considerable loss of power or response:


    Both the ACE Laguna 90 and the CSG MXP Touring86 exhaust are proven to pass Laguna 90dB days with either Turbo or Supercharger kits, plus ACE header and ACE front pipe.

    For applications where a higher limit of 100dB is present, you take advantage of additional weight savings by fitting the ACE Laguna 100 Exhaust:
