E46 reinforced front subframe exchange program

The stock e46 front subframes live a pretty hard life. Filthy subframes with ripped motor mounts and weak sway bar mounting locations are a pretty common issue in the e30, e36 and e46  world. Engine mount tab failure such as bending and cracking can result in a costly repair. The motor mount area is very thin and weak from the factory. Reinforcing this area is a must-have if you are using stiffer or solid engine mounts. This is especially true with motor swapped or high horsepower e46's. The heavier and more powerful engines (LS1, S5X, M30, M60, turbo etc etc) cause more stress on the subframe and are likely to cause a failure. That's why we offer this subframe exchange program. Simply send us your straight and undamaged e46 subframe, get a reinforced front subframe back (with your choice of color for powder coat). Its as "bolt up" as it gets! 

These are a must for track/race vehicles.

E46 reinforced subframe features:

• Powder coated (black is standard, other common colors are available)

• Fits all e46, Including M3

• Reinforced engine mounts (including gusseted section)

• Allows safe use of solid/stiff motor mounts

• Repair of minor existing damage (please inqure first)

• Reinforce of known weak point subframe

• Inexpensive insurance against failure

This is a core exchange program. Send us back your STRAIGHT core and we will refund you $150.

How long does the modification take?

If we have them in stock, we will ship them the day you place your order. However it could take up to 4-6 weeks (depending on core availability) before your item ships. If you have a time constraint please contact us first or send us your core for re-work. When you receive your subframe and install it, you can then ship your old straight, undamaged, subframe back. If you choose to send your core in we will give you back the $150 core charge. Once we receive your core we refund you within 7-10 days using the method you paid with.

Providing us your core is the best way to ensure it is identical to what is on your car. While E46 subframes are all functionally the same fit there are minor differences (x-brace mounting, transmission guards etc)  across models that we do not differentiate between. All of the subframes we stock will work across the model cars that are listed here, but if we are not re-working your subframe expect that there may be some minor differences between what you receive and what is on your car. 

CORES MUST BE RETURNED IN 30 DAYS FOR A REFUND. ALL CORES RETURNED AFTER 30 DAYS ARE ONLY ELIGIBLE FOR STORE CREDIT NO EXCEPTIONS. ALL CORES MUST BE IN OEM UN MODIFIED CONDITION, WE DO NOT ACCEPT PREVIOUSLY MODIFIED COMPONENTS FOR CORE. SERIOUS RUST, MAJOR CRACKS, OR BENT SUBFRAMES ARE ALSO NOT ACCEPTED AS A CORE. SOME MINOR CRACKING MAY BE ACCEPTABLE PLEASE CONTACT US WITH PHOTOS FIRST.

You can also add our front control arm ball joint reinforcement kit as an added option! Picture of that option is below!
