      TT/R32 Rear Adjustable Control Arms

      Click on the picture to visit our product page for up to date pricing info.

      Poly Ends Now With Relocated Zirc Fittings for Easier Access !

      Got a lowered TT or R32 ? Then you already know how the camber and toe become completely out of sorts, causing poor handling and expensive tire wear the more its lowered.

      The GruvenParts adjustable control arms allow for complete rear wheel alignment and feature the following :

      Choose from a zero deflection high radial load PTFE lined inboard spherical joint with protective dust boots preinstalled over specially machined bushings. The fit of the boot over the spherical joint and bushings is nearly water tight!


      A poly bushing inboard end made from heat treated 4340 forged chromoly housing, thread in grease fitting, zinc plated steel protective sleeves, and race grade greaseable black polyurethane bushings from Energy Suspension.

      You decide which set up you want ! The zero deflection spherical joints are suited for serious track abuse while the poly bushing ends are better suited for daily drivers.

      All GruvenParts control arms feature the following :

      Super strong, heat treated 4340 aircraft grade chromoly rod and ¼” thick U-Joints with machined, internally lubricated (molybdenum disulfide) threads. No weak aluminum is used for these parts (aluminum threads wont hold up).

      Distinct proper wrench adjustment flats machined into the bars which allow for 2” of length adjustment while on the car. There is no knurled hand adjustment nonsense here, ours are simple to adjust.

      Thick, durable powder coat finish (and zinc plating on the poly bushing ends) in your choice of high gloss black or Bilstein jazz blue.

      Made right here in Atlanta, Georgia by our FAA approved commercial aviation machine shop working on state of the art CNC mills and lathes. You wont find many shops working at our level, and you wont find higher quality anywhere !

      We know the economy is tough right now, so we are offering these at prices well under our competition. Buy 2 sets and save !!!

      This product fits Audi TT (2001-2006), Audi A3/S3, VW R32 (2004), VW Golf 4motion and 4motion Variant, VW Bora 4motion and 4motion Variant and replaces P/N 1J0-505-323L (1J0505323L) and 1J0-505-323N (1J0505323N).

      ***Save Big $ when buying these in conjunction with our Adjustable Rear Swaybar End Links and our Adjustable Front Swaybar End Links

This part replaces thermostat housing P/N 021-121-117A (021121117A), adapter P/N 021-121-133D (021121133D), and thermostat cover P/N 021-112-121A(021112121A).

      Billet VR6 Crack Pipes for ALL VR6 Engines Corrado thru R32!


      12V and 24V VR6 Coolant Pipes aka Crack Pipes

      GruvenParts.com was the 1st to build this part and it’s what started us off! We manufacture this pipe EXACTLY to match the OEM part shape so there is NEVER a fitment issue. Be careful when considering other billet pipes which do not match the exact shape of the OEM pipe. The fitment of this part is tricky and the shape MUST BE IDENTICAL to the OEM part to ensure correct alignment between the water pump and thermo housing.

      If you have a billet crack pipe in your VR6, chances are it was made by us. Hand crafted in our Aerospace shop using O-rings from the Boeing 777, proven by many hours of track time, it's the highest quality crack pipe you can buy. It's on all of our track cars and has withstood countless hours of track abuse! Our pipe has a modular design which allows you to plug the oil cooler feed line with a ¼ NPT plug if installing an external oil cooler. Ours can also be ordered with a chrome plated drain valve for quick and clean coolant flushes. The pipe can also be ordered with a brilliant chrome finish for those seeking the ultimate engine bay bling!

      If you dont want to do this job again, buy the LIFETIME WARRANTED GruvenParts.com billet CrackPipe !

      Billet VW/Audi 24V 2.8/3.2/3.6L Oil Filter Housing Caps !

      Modular Billet Aluminum Oil Filter Housings For VW And Audi 24V 2.8/3.2/3.6L Engines !

      This product is intended to replace VW/Audi Part Number 071-115-433 (071115433). Please check the OEM part number of your oil filter housing cap before ordering. You can do this easily by calling your dealer and giving them your VIN # and asking them to tell you the part number for your oil filter housing cap.

      Just like our best selling billet MK2/MK3/MK4 VR6 and 4.2L V8 oil filter housing caps -- This one was worth the wait ! Never, but NEVER break a flimsy plastic oil filter housing again. Or deal with the unsightly leaks created by the cheaply made (yet expensive) plastic OEM housing cracking and deflecting. We made this one the way VW and Audi should have – from A SOLID BLOCK OF ALUMINUM, by God!

      First, we start with a massive solid chunk of Aircraft Grade 6061-T6511 Aluminum. The section is delicately placed on one of our special CNC machining centers and precision cut to EXACTLY match the OEM plastic housing. The metal gods (well, in this case, one of our highly talented CNC programmers) has programmed elaborate steps for the very time consuming and expensive operation of profiling the special buttress threads into the housing using the exact DIN spec thread cutting tool required for a perfect seal.

      This part comes with 2 threaded holes (M10x1) with steel drain plugs installed in both as shown in the pictures. You can therefore choose to install a VDO pressure sender in the center hole (VDO P/N 360 015) and/or a VDO temperature sender in either the outboard threaded hole or center threaded hole (VDO P/N 323 423). Please note the pressure sender will only fit in the center hole due to its size. Either hole can be retained as a drain. Please note the temperature and pressure senders are not included, you can source those from many retailers (such as Summit Racing). This DOES include the 2 steel drain plugs.

      This product is intended to replace VW/Audi Part Numbers 071-115-433 (071115433) or equivalent. Please check the OEM part number of your oil filter housing cap before ordering. You can do this easily by calling your dealer and giving them your VIN #.

      Application Guide :

      Audi A3 8P All 3.2L
      Audi A3 8P All V6 3.2L
      Audi TT MKI All 3.2L
      Audi TT MKII All 3.2L

      Volkswagen CC 4Motion VR6
      Volkswagen CC FWD VR6
      Volkswagen Eurovan T4 All VR6 24v
      Volkswagen Golf IV All VR6 24v
      Volkswagen Jetta IV All VR6 24v
      Volkswagen Passat B6 All 3.6L
      Volkswagen R32 MKIV All All
      Volkswagen R32 MKV All All

      Special Note At The End :
      You will need to carefully remove the sping bypass valve located at the base of your OEM plastic oil filter cap and install it into this billet housing cap. Carefully push down on the bypass valve inside your OEM cap and deflect the spring to 1 side fully. The whole bypass valve will then unclip from the plastic OEM cap. Install it in the same position into our billet cap. It is easiest to do this on a work bench, just use a suitable deep well socket to fit against the spring bypass valve, face the cap down (bowl at top) while aligning the bypass valve with the metal tangs on our billet housing. Then apply about 10 lbs of force downward while wiggling side to side gently. Your existing bypass valve will snap into place over the metal tangs in our housing. YOU MUST INSTALL THE BYPASS VALVE. If you do not, the oil will simply bypass the filter and will not be cleaned.

      When installing this cap into the oil filter housing, please clean all threads and use a bit of anti-seize on the threads of our part to make this easier to remove during your next oil change. Also, be sure to lubricate the o-ring with some fresh oil so it is not torn during installation. This part doesnt come with the O-ring -- that comes with the filter itself.
