This is a continuation of the Part 1 installation of new Adaptec Speedware wheel spacers on my 991 C4S.

If you missed it, you can find Part 1 here: 991 C4S Wheel Spacer Install - Part 1

With the two rear spacers installed, wheels and wheel-wells all clean and shiny, I moved to the front-end.

As mentioned in Part 1, I chose a setup that includes 15mm Rear spacers, and 7mm Front spacers. In this Part 2 post, I am installing the 7mm spacers to the front.

I removed the front passenger-side wheel. I had to hit the wheel a number of times with my rubber mallet to free the wheel. Made my case for using a tiny bit of anti-seize!

Here's the wheel removed:





As in all cases, I got my wire brush out and removed as much of the rust and other build-up as possible, then cleaned with some brake-cleaner. I then applied a tiny amount of anti-seize to the hub, then pushed the spacer into place.



I used my rubber mallet to tap the spacer into place. All fit very snugly and well. I was happy!

Next I applied a tiny bit of anti-seize to the spacer plate facing, and mounted the clean wheel over the hanging pin.

I tightened everything up by hand, then lowered the car. Moving over to the drivers side front, I performed the same procedures, mounted the plate and wheel, and lowered.

I immediately saw a noticeable difference in how the wheels/tires fill-out the wheel wells! More on that in a moment.

With the car on the ground entirely, I went from wheel to wheel around the car applying torque to each bolt -- 118lb/ft.

And we are done! Overall, with the wife away and the kids in bed, this was a simple, 5-beer project! 1 beer each wheel, 1 beer to celebrate finishing without damaging anything! lol

Unfortunately I did not do a great job taking before pictures to compare to, but here is what I have...

This is stock, "before" the drivers rear wheel spacer was installed:



And here is an "after" view of the same wheel well:



And here are some "After" shots of each wheel well around the car:

And finally, following are some random shots of my car taken the day after completing the installation:








Thanks for reading! Hope others will find this useful. I will cross-post to the DIY section shortly.

Looks Great.

 

Nice job. Thanks for the how to. They fill the wells up a lot more now! Very nice.

 

Love the stance with the spacers! Great work.

 

Really, 118 lb/ft? Seems a bit high. Also, you should ALWAYS torque the lug nuts in 25%/50%/75%/100% (of max torque) increments, and going in a star pattern.

Added since you seemed to have wanted to be complete.

 

Thanks for adding the clarification about tightening procedure -- yes, follow a star pattern. I didn't mention that specifically in the detail, but when I remount each wheel I first finger tighten the bolts in same pattern, then follow the pattern several times to tighten to limit. I then lower the car and THEN use the torgue wrench to set to recommended ft/lb.

The 2014 991 C4S owners manual I have states repeatedly (pages 252, 253, and 256) to tighten wheel bolts to 160 Nm or 118 ft/lb -- so that is what I did. Is there a different torque that I should use?

 

Honestly in ownership of 3 Porsches back to back, I've never had the occasion to remove the wheel so I never bothered to check recommended torque. I'm use to 88 lb/ft as the general rule. Now I'll have to go check my owners manual. That's with many BMWs and in Germany where I changed wheels twice annually between summer and winter.

I prefer to set torque with the wheel touching the ground to keep from rotating, but not full weight on the wheel. Once the car is on all fours, I loosen each bolt and reapply the max torque one at a time, also in the same star pattern.

Also, when I lived in Germany, when you drive to a dealer for service, some guy usually walks out with a torque wrench at some point and ensures all bolts are torqued correctly. Germans are safety crazy.

 

I was looking exactly for this! Thanks for posting this. Definitely not "too simple" for me to warrant a DIY

Thanks again!

 

With the spacers and new stance, are u going to/able to lower the car now with lowering springs?

 

My plan is to lower with the H&R set sometime later this summer... I have stock "S" now that came with PASM, so already 10mm lower than non-S car. The new springs should put my car down at about same stance as (...actually can't recall specific, but I think it may actually be 5mm lower than...) S-PASM equipped car.

We'll see. I plan on DIY for the spring set when I get to it, so will post update when it happens.

 

Hello Jawells, I have a similar set up with my S with aggressive wheels, but I am afraid to lower it because I am worried that the rear wheels will rub the fender if too low. Please do let us know how you make out.

Here is a photo of my car on the weekend during PCA Auto X during a lean. Currently with stock S springs, I am fine, but with lowered springs, I think it might rub. I called the wheel maker and they actually suggested against lowering as they too fear it may rub.

 

Mine was lowered with H&Rs + I have wheel spacers and no rubbing.

 

Hi Capsfan do u remember the size of your spacers? How do you like the ride with the lowering springs?

 

Viper- like the wheels! What size / offset? That makes a diff. I am still running with stock, OEM S wheels. Also, is your car a 2S or 4S variant? I have the 4. The rear fenderwells are pushed-out further, and the lip is rolled by the factory. Not sure if that is the case on the 2 variants.

Love the pics!

 

Hi Jawells, thanks for the compliments! My wheels are MRR RW5: http://www.mrrwheels.com/rw5.html I did not realize the awesome offset of these wheels until they were actually installed on my car and I was like, WOW!!!, what a difference that made to the look and stance of the car!!! They were not expensive at all and IMHO, great bang for the buck! I am not sure if my car has rolled fenders or not though. It is just a 2S, and I do want to lower it a bit with springs, but worried about rubbing on the fenders since the wheels do stick out quite nicely.
