Default ISC Wheel Adapters

Product: ISC Wheels adapters

Style Reviewed: Gold adapters, 15MM wide

Vehicle used for review: 2009

MSRP: $ 299.00

Where to buy: http://www.iscsuspension-na.com ( I got mine from AJW Performance )

Description according to ISCs website:

Finally, A name brand Subaru wheel adapter that works well and is affordable! No sense in paying 450.00 for competitors adapters any longer. This set ( 4) of bolt pattern adapters will allow you to bolt STI fitment wheels (5x114) to your WRX (Legacy, Forester, BRZ or any 5x100 Subaru)! These are 15mm wide.

The ISC Subaru wheel adapters fit all 5x100 Subarus. Precision CNC-machined billet aluminum bolt pattern adapters, and twenty special low-profile lug nuts. The adapters are hub-centric for both the car and wheels. Offered in both a anodized ISC gold, or a stealth black finish. ISC Logo is engraved on spacer as well.
Materials Used:
Adapter: CNC 7075 light weight high grade aluminum

Included Hardware: M12*1.25, Grade 10.9


Initial Impression: Once i opened the box, i could see the outstanding anodized gold finish peeking out from behind the bubble wrap. everything looked great, and i couldn't wait till i could put them on my car.


Here is a quick step by step with pictures that i took throughout the installation process.


1. gather all the parts that you need for the install




2. I also did a quick test fit of the adapters into the back of the new wheels, just as a double check. As i expected, the ISC adapters fit flawlessly into my BBS.



3. Get the car off the ground and remove all 4 wheels. If you don't have access to a lift, a jack and 4 jack stands works just as good.



4. Once all the wheels are off, take a wire brush and clean up all the surfaces the adapters will be mating to.

5. Add a little bit of anti-seize around the center bore pilot, so that the adapters will come back off when it is time for the winter wheels to go back on.



6. Install the spacers over the car's studs with the supplied hardware from ISC. Tighten these bolts in a cross star-like pattern, just as you would tighten wheel lug nuts. Torque to 86 ft-lbs.



As you can see from the above photo, the lugs are sticking out pretty far past the adapters. This will cause problems when trying to mount the wheel,causing the wheel to hit the studs before actually tightening down, so be careful. According to ISC, wheel stud modification is only required with the 15 mm adapters and the 25 mm adapters require no modification to your stock wheel studs.

7. My BBS wheels that i am mounting on the car have pockets on the back of the wheel, but were not deep enough. so, i had to trim 1/4" off of each stud. Also, cutting this little amount off allows me to still run my winter wheels without the adapters installed.To do this, i used a cutoff wheel on an air tool, but if you are good with a sawzall, that will work too. After all 20 studs were cut, i used a M12 x 1.25 thread chaser to clean up any and all threads that may have gotten damaged. This was a very easy process, just time consuming due to the number of studs. Re-install the adapters on the car.



8. Test fit the wheels on the car. Take special notice to where the wheel meets the mating surface of the adapter, making sure that it is flat and there is no clearance issues with the lugs hitting the wheel.

9. If everything looks good, you're ready to put your new, 5 x 114 STI bolt pattern wheels on. Be sure to torque all wheels to 86 ft-lbs. Because the wheel adapters are new, it will take some time for the new studs to seat properly into the aluminum body of the adapter. I torqued all my wheels as usual, then went around the car again and re-did them all again. I then drove the car around the block, and re-torqued them a third time. i also re-torqued them after 100 miles of driving, just to be sure.





After driving on these for almost a week, there is nothing but positive things i can say about these. All winter i struggled with a new summer wheel decision and the lack of variety in the 5x100 bolt pattern. Once i heard that ISC had the 5x100 to 5x114 adapters coming out this spring, it increased my options ten fold. I love the way my car looks with the new wheels, and that wouldn't have been possible without the quality and affordability of these adapters from ISC. TWO THUMBS UP FROM ME!!

is it advised to use spacers if i'm tracking my car?

I mean I can always take them out for track and put them back on for street driving..
i hear them being bad for wheel bearing, but wouldn't it be the same thing if you got lower wheel offsets?

25mm ISC Spacer/Adapters installed with 08+ STI BBS wheels. 18x8.5+55 offset. +30 actual offset after the spacers. I'm running 245/40/18 tires.
Stock alignment, Stock Suspension/Height.

I need a roll in the rear for sure. :P It's rubbing on bigger dips/hard turns, especially with a full load.

FYI, you will not have to cut your oem studs if your wheels have the pockets in the back, like OEM wheels do.

The pockets are too small on the STI BBS wheels.

They still have to be notched out on the STI Enkei's (there's a forester guy that did it).

20MM will def clear, and obviously I have no issues with the studs with 25mm.

Good notes right there! Maybe just the earlier models had bigger gaps?

I guess so, not really sure!
I just know for the GR/GV chasis wheels, there isn't enough room for sure.

Evidence (15mm with GR Sti BBS wheel)

I recently purchased the ISC Suspension 15mm wheel adapters from AJW Performance.

Product: ISC Wheels adapters

Style Reviewed: Gold adapters, 15MM wide

Vehicle used for review: 2001 Subaru Forester L

Wheels used for review: 2005 STI Gold BBS 17x8 et 53

Initial Impression: Once I received these adapters and inspected them I noticed that they seemed like a quality piece. The machining/anodize seemed to be of great quality. They fit on the hubs and into the wheels perfect. However I did have to cut back the studs for the wheels to fit perfectly. I knew I was prob going to have to do this when I ordered them. No big deal. My other set of winter wheels (Rota Boosts) still fit on the lugs perfect.

Overall Impression: I am very satisfied with the adapters and would recommend them to others. I kind of wish I went with the 25mm adapters just for a more aggressive fitment and lack of having to cut the studs. But its all good and I am happy. I have about 1k miles or so on them now.

A few installation notes:
-CLEAN your hubs thoroughly (car and wheel). I experienced a bit of steering wheel vibration because I did not do this (pulled winter wheels off and put the adapters on).

-Also torque them to the hub in a step sequence. I did 50ftlb then 75ftlbs then 90ftlbs.

-Recheck the torque on the wheels after finishing all the wheels and then again after a bit of driving. The lugs will fully seat into the adapter a bit and may cause your lugs to come loose initially.

They have been working out really great we've found in combination with the cosmis racing wheels to get those wide wheels on our 5x100 buddies into a subaru friendly offset!

Product: ISC Wheels adapters 5x100 to 5x114

Style Reviewed: Black adapters; 15MM

Vehicle used for review: 2000 Subaru Impreza 2.5rs coupe

Wheels used for review: 2005 STI Gold BBS 17x8 et 53

Initial Impression: The machined anodize are most certainly of great quality, definitely impressed! Having them hubcentric is also an added piece of mind. Sit perfectly on the hub.

Overall Impression: Extremely satisfied with them, zero wheel vibration!

Notes:
For GC8 owners; you will need to cut about 5mm off your studs to clear the BBS, unfortunately the pockets behind the wheels were not deep enough. Nothing my little Dremel couldn't handle!


Here they compliment the ISC coilovers

interesting, thanks for the pics/review!

I hear that running spacers though isn't good in the long run but maybe come winter i'll be getting myself some BBS goldies and not at the absurd 5x100 prices!

There was a mix up when the info was originally written, they are indeed 7075-T6. We'll get t work on updating this, thank you for bringing it to my attention.
