Default 997.2 C2 + Turbo II Wheels + Eibach + 7mm/15mm Spacers + Michelin 235/35 305/30

I finally decided to lower my 997.2 C2 (non-PASM) with Eibach springs kit and I am about to pull the trigger. I'm in need of four new tires and I will save some bucks by doing it all together.


Anyone running this combo? Any thoughts? Photos?


997.2 C2 Base (non-PASM)

OEM Turbo II Wheels:
Front 8" x 19" ET57
Rear 11" x 19" ET67

Michelin Pilot Sport 4S:
Front 235/35 19
Rear 305/30 19

ECS Wheel Spacers:
Front 7mm
Rear 15mm


Should I go wider on front (245/35 tires)? I am leaning towards 235 because 997 C4 came stock with 235 front and 305 rear, and I like the look of a low profile tire on front and a big fat tire on rear.

Thanks in advance.

Is the front 8 or 8.5? 52 on the back will be nice with the increased negative camber form the drop. 50 on the front sounds great if the 8.5. I am running 245 and 305 on a C2 with no PASM.

Fronts are 8".

OEM Turbo II Wheels:
Front 8" x 19" ET57
Rear 11" x 19" ET67

Are you on Eibach or H&R?

For the minimal extra grip that those 305s are going to offer, I'd just as soon get the standard narrow body size (295/30/19) and save $65.

Actually, I am going with 305 just for the look. I do not track my car.

This is the look I want on rears (305/30 and 235/35 - MYW's car):

EC, do 12mm spacers in the front, 7mm is too mild... i am running 15mm spacers in the front (identical wheel sizing and offsets are yours).

having seen many 997s with the 7/15mm spacer combo in real life, i never understood why it seems to be the internet norm. when i bring it up to the owner that the 7mm front is too mild as there is still so much more room they all end up agreeing.

imho, 12mmF/15mmR spacers will look fantastic. 235/35/19 front + 305/30/19 Rear plus ur new springs will look amazing. the c4/c4s 997s on 8"F/11R" wheels ran the same oem tire size setup.

Don’t know where it was decided that 7mm on the fronts was ok. When I had the original wheels on my car (same size as OP), I put 10mm on the fronts and there was still plenty of room. Ended up replacing them for 15mm and it looked great.

Regarding the size of the rear tires, it will also depend what brand and model of tire you are getting. I recently installed Michelin PS2’s and the 295 looks awesome on the back with 11 inch wide wheels. With that tire I wouldn’t recommend going wider than 295.

Below you can see a pic of my car lowered with Eibachs with my previous Continental DW 295’s on the rear. My new PS2 are wider even though they are the exact same width. Unfortunately I don’t have a picture with the PS2’s, but I’ll get one this weekend after I come back from a business trip. My rear offset is ET50 which is the same as having 17mm spacers on the back.

Ok, plan upgraded to 12mm front and 15mm back.

ATSR I think you have a good point about the tires. MYW, are you running on Michelin Pilot Super Sports?

Thanks for the inputs.

I am running a very similar set up on my 09 C2 Cab non PASM.

I actually have Turbo IIs that came off of a Turbo which is a WB wheel and requires the 305s in the rear. I’m running S-04s since I did this when Michelins were out of stock everywhere in the summer of 16.

With the WB wheel in the rear I’m running no spacer in the back and offset is perfect. Up front I am pretty sure I am running a 15mm spacer and they line up perfectly with the rear stance.

I’m running with Eibachs and am extremely happy.

Thanks for confirming 305 PS4S works fine. The Turbo WB is 11,5" wide ET51... or the same as NB 11" wide ET67 + 16mm spacers.

305 on my 11" NB wheels + 15mm spacers should do the job.

997.2 turbo WB is 11 inch not 11.5. only the 997.1 turbo wheel rear wheel and the 997.1 sport rear wheel wheel is 11.5. all other oem 997 rear wheels are 11.

the 997.2 turbo II WB rear 11 inch wheel (identical wheel on both the turbo + c4s), when compared the 11 inch 997.2 turbo II NB rear wheel (an option on the c2s) has the exact same wheel design and concavity.

they just add 16mm of extra spacer material into the wheel hub for the WB wheels (+51 vs +67); hence forth keeping the wheel mold (and costs) the same.

15mm rear spacers and 12mm fronts (if you plan to lower) is what i would suggest. if you are leaving oem height you can go 15mm F/R and you will have zero issues and have pretty much same stance as my car.

You are absolutely right; 997.2 Turbo II WB wheels are 11" wide and not 11,5". But the math is right (I believe) which gives 16mm spacer (67mm - 51mm).
