Aftermarket tuners and fabricators are wasting no time in customizing and modifying the F30 3 series sedan. LTBMW has certainly wasted little time in customizing the look of their barely two week old Melbourne Red F30 335i. What you see inside features the following mods:

Front license plate bracket delete
Front bumper reflector delete
Painted roof
Painted rear diffuser
Painted grilles
Custom lowering springs
5mm spacers all around

The terrific photos are by site member jzhang.

5POST member delvek reviews his Hartge ECU remap for the 550i, which he had performed on site at Hartge’s facilities. Hartge’s official stats for their 550i ECU is 360 kW (490 hp) / 5500 rpm 720 Nm (lb-ft 531) / 6400 rpm.

The results? The Hartge engineers were able to record a 80kmh (50mph) to 180kmh (110mph) run in just 7.2 seconds. Delvek’s previously stock 550i took 11.4 seconds to reach the same speed!

With the 3 series traditionally having the largest aftermarket support of any BMW model, it usually doesn’t take long for the first aftermarket parts to become available. And one of the first parts are usually suspension components.

H&R has now released its F30 springs application for the 2012 328i and 335i sedan. The lowering springs come in two varieties — Sport Spring and Super Sport Spring, with the latter being a more aggressive lowering.

The H&R Sport Springs (Part #28878-2) lower the F30 by 1.2″ front and 1.2″ rear.
The H&R Super Sport Springs (Part #28877-2) lower the F30 by 1.75″ front and 1.6″ rear.

Retail MSRP is $389.00 for both sets.

H&R also makes a whole catalog of wheel spacers for the F30 and BMWs, in many sizes – … CONTINUED

We bring you the first dyno results from a 2012 335i (F30) sedan, performed by Challenge Mfg. USA (GTM_Challenge) on their recently delivered 335i. The F30 335i is powered by the N55 6-cylinder TwinPower twinscroll turbo engine and its factory quoted power figures are 300hp / 300lb-ft.

The 335i N55 dyno run resulted in 270whp and 273lb-ft torque. Note that the dyno was performed on a AWD Dynojet with linked AWD rollers. On a normal rear-roller-only system the numbers would be slightly higher (probably 5-10hp) given the less roller weight that would need to be moved.

What does this translate to in terms of crank HP (for comparison to the factory quoted figures)? Taking 275whp and 278lb-ft as the starting point and assuming a 15% drivetrain loss, it … CONTINUED
