  1. Lowering a drag car

    I just put 18" Apex wheels on, 305/35 rear and 275/35 front. This increased the wheel gap and I'd like to close it up a bit. The car is a purpose built drag car and I heard lowering drag cars isn't ideal. What are my options here, can I run an adjustable spring kit or do I need a proper coil...
  2. 18x11 Apex SM10 with a 305 tire on stock suspension

    I am having a hard time matching a good tire combo with the Apex SM10 rims in 18x10 +30 front, 18x11 +40 rear. Following the fitment guide I can't find a street/track setup that uses a 305 in the rear without modifications. I would prefer to run a 275/285 up front and a 305 in the rear. I am...
  3. Crankshaft position sensor connector

    I'm trying to finish installing Reflex, but I can't get the connector off of the crank position sensor. I can get my hand on it, but I can't seem to figure out how to free the connector. Does anyone have any guidance or better yet, a closer image of what the connector looks like? Image for...
  4. Are our axles the same as Z4 / 330 / 430 etc?

    After some digging, it seems we may share axles with the Z4, 330, 430 etc and they didn't use the beefier ones from the M340. I had my DSS axles delivered recently, but there was no rear axle dust guard included. I ordered the last two in North America and they are 4 days to two weeks out. BMW...
  5. Turbo guard vs filter for 6870

    My 6870 kit just landed and I don't want to run the turbo without some type of protection. I am stuck between a filter and turbo guard. The two biggest questions I have right now are how much power am I going to lose running a filter, and am I being too anal thinking I need a filter and should...
  6. Pure Drivetrain Stage 1 vs Stage 2

    Hi all. I have a KLM 6875 turbo kit coming, all the fuel mods and axles/wheels to support it. I am stuck on what trans would be best for my application. Pure Stage 1 is good for 1000hp/850tq, Stage 2 is good for 1200/1000. I know the turbo is good for ~1200 but I honestly don't see myself...
  7. Swapping built axles in driveway?

    I have DSS axles on order, they are about 2.5 weeks out. They are going to send them to me, and asked that I send mine back at the same time. I'm curious how difficult this job is in the driveway? Local shops don't seem interested in taking the task on, and I'm running short on time. Would...
  8. Will two drag radial tires fit in the trunk? Weld 17x10 w/ 305/45R17

    I have 17x10 Weld Weldstar Beadlocks on the way, going to wrap them in 305/45r17 MT ET Street Rs. Will these fit in the trunk? I'd rather not drive them to the track and get caught in the rain if possible. Also, anyone on the same setup I'm curious how your experience has been?
