GruvenParts.com provides the complete solution for your VW MK4 R32 or Audi MK1 TT. We offer a full line of adjustable rear control arms and front and rear adjustable stabilizer bar end linkages. These products not only solve the issues with aligning a lowered vehicle, they also work great to tweak alignment on non-lowered vehicles! Please read the descriptions below regarding the various product options and note that you can save $ when buying 2 sets of control arms, as well as buying the control arms in conjunction with the front and rear adjustable stabilizer links.
The GruvenParts adjustable rear control arms allow for complete rear wheel alignment. You can choose between 1 set to adjust camber only, or 2 sets which allows for camber and toe adjustment. 2 sets is recommended if you want to maximize rear tire life and is mandatory for drops greater than 3/4".
You can decide between the Poly Ends and the Spherical Ends on the inboard (differential) end.
You decide which set up you want. Either work well for both street and track, but the spherical ends will perform better on track due to zero deflection (but may be a bit louder). IE – if you want a Cadillac ride, go poly end. If you already have a lowered, stiff set up, you wont notice the added rigidity of the spherical ends.
Additional features which set our control arms apart from the copy cats :
This product is sold in sets of 2 arms. Buy 1 set to adjust camber only while 2 sets will allow for camber and toe adjustment. For drops greater than 3/4 inch, we recommend 2 sets as this will provide you with all the adjustment you need.
This product fits : Audi TT (2000-2006), Audi A3/S3, VW MKIV R32 (2004), Golf 4motion and 4motion Variant, VW Bora 4motion and 4motion Variant and replaces OEM P/N’s 1J0-505-323L (1J0505323L) and 1J0-505-323N (1J0505323N).
** Please Note : Some vehicles have short (less than 80 mm) outboard bolts. Because our control arms are made from a thicker U-Joint material than stock, it is necessary to install our control arms with 80mm bolts on the outboard ends. If your vehicle needs new outboard bolts (or inboard bolts), please visit the Extra Hardware page below to buy individual parts after placing the control arms in your shopping cart.
**Additional Purchase Options :
Save a decent bit if you also buy these great products along with 2 sets of our adjustable rear control arms :
Extra Hardware - headlight leveling brackets, longer bolt kits, or any replacement hardware for our rear control arms.
These parts are warranted by GruvenParts to be free from any defect for 1 year. The spherical ends will not be replaced if they develop slight (less than 1/32”) wear, as that is normal as the PTFE liner and ball mate together. If you have any issues or concerns even after the warranty period, please contact us directly.

Got these with poly ends to get my rear camber and rear toe in line. Went from -3.5 degrees and -2.5 degrees to -1.5 degrees, and there was still plenty more adjustment left. Shipping was quick. Recommend getting new bushings and bolts for the knuckle/spindles, chances are the bolts are seized in there.
Have been driving for a week now and the car feels great. Will try to update in a years time.

Great quality. Make sure to order an extra set of m12 x 1.5 x 80 mm to replace the stock 75 mm bolts. The outside flanges are thicker than stock so the extra bolt length is required.

Able to now get both toe and camber into spec. Replaced a pair at a time which was a mistake should have listen to you guys.
Lowered the car with h&r sport springs and the camber was out but the toe was ok.
Replaced the lower set of control arms and then the toe was out so had to do the uppers as well....so save the money and order both pairs if you have lowered the car as outlined on this website!

Control arms have exceptional build quality. Ends are durable and able to be lubed for maintenance. Allow for complete adjustment. Highly recommend for anyone looking for extra adjustment. My R32 has 150K miles and has reached max alignment on factory control arms. These are great upgrade. Caution when taking to shops for alignment. In my run in with a national chain I had a lazy tech who damaged my set but not related do to the product. I advise to mention when at the shop too specifically tell them what needs to be done and how.

I purchased these control arms with scepticism as I am in Australia, but am completely blown away by the build quality and professionalism from the company and product standards.
They fitted perfectly and gave all the adjustment required to bring in the suspension to near perfect alignment.
Thanks again to the team at gruven parts, an amazing product!

I received my control-arms and front endlinks today. I'm really satisfied with the quality of those parts. Plus they look nice! I can't wait to install them.
Shipping was fast.

Got the arms installed last week. They enabled dialing in of alignment that factory parts were no longer capable of. Took the car out for 1000 miles of driving over the weekend, then back in and checked alignment. Off by some, but still within rated spec. Shop dialed 'em back to perfect. Will let them go now for another few thousand and check them again. Expected some movement after the first 1000, but they should be stable now. Will follow up later (if possible).

Product seems to be of good quality, well protected during shipping, very satisfied with the result on the car.
A little bit slow shipping, both slow at USPS and it took a bit of time until it was delivered to USPS, wasnt a problem as i was not in a hurry.

Thanks Erik, we are glad you have them installed and sorry for the shipping time. Normally USPS gets these within USA within 2 days, much faster than UPS. Anyhow, please post some pictures in the forums installed, its always fun to see these great parts going into our high end customer cars!
