When dismantling a suspension strut sometimes the securing nut can be difficult to access and the central strut itself needs to be held still while the nut is undone. This new Shock Absorber Tool Kit is designed to overcome these problems and make the job quick and easy.
The go-through design of the sockets and ratchet design allows the strut lock extensions to go right through the middle of the ratchet and socket. Five different strut lock extensions are included, to fit a variety of applications. Seven go-through deep sockets (16, 17, 18, 19, 21, 22 and 24mm) are included, plus a sliding T-bar.
Once the spring is compressed and the top plate is free, simply choose the correct strut lock extension and socket. Then fit the socket and the ratchet handle, and fit the strut lock straight through. The central strut is held steady, and the securing nut is quickly removed.
Specifically designed for repairing and replacing shock absorbers and struts
Contents: 7 - Go Thru' deep sockets: 16/17/18/19/21/22/24mm

Shark Injector V2.0 Performance Software includes:
Performance software is a must-have upgrade on your E46 M3 and you won't find an easier and better software solution than the Shark Injector. This device plugs into the car's diagnostic port and flashes new performance files into your car's engine computer (ECU). There's no removal of the ECU and shipping, no cables, no laptop required - only a battery charger! Installation takes just a few minutes and your engine will perform like never before.
Building on the super-simple-to-use original Shark Injector, our new V2.0 capitalizes on this simplicity while heightening the driving experience with more power! Have a tune from the previous Shark Injector version - and want more power? Upgrades from Shark V1.0 to V2.0 are available. Give us a call and we'll be happy to discuss upgrades.
Our newest M3 performance software was developed on the dyno to create maximum power and torque using premium 91 octane fuel and revising the torque limiters in the ECU, although even more power is to be had using 93 octane fuel. The software makes changes to the ECU's maps and algorithms for fuel injection, ignition timing, VANOS and camshaft movement, and transitional fueling. We modify the maps for part throttle and full throttle so you get better response and more torque at all RPM, with serious power to be found over 4,000 RPM. By fine tuning these maps we've been able to improve the S54 engine beyond what BMW did by making more power and torque and a smoother-running engine. The top speed limiter is removed, and rev limiter lifted to 8,250 RPM.

Power and Torque Gains
Stock software: 283 whp / 232 wtrq
Shark Injector V2.0: 301 whp / 243 wtrq
Peak gain 18whp and 11wtq
(note: the max gain (biggest improvement) is 22whp at 6400 RPM, with 16wtq at 5600 RPM)
The Shark Injector plugs into the diagnostic port inside the E46 cabin. With the battery charger supplying power, press the Upgrade button and within minutes the ECU is reflashed with the new performance tune. No other software product on the market comes close to how easy it is to install. You can use the Restore button to re-install the stock BMW software at any time. Detailed instructions are included. Other tuners require you to remove the ECU and ship it to them or use a laptop to read and write a new file. The Shark Injector is ready to install right out of the box!
