My Race wheels and slick tires are here!

Got this set for the next SCCA Autocross season. Making the switch from street tires to race tires for the first time this year.

Wheels: Enkei PF01 (18lbs front, 20lbs rear)
18x8 +35 Front
18x9 +35 Rear

Tires: Hankook Z214
245/35/18 Front
275/35/18 Rear

Yet to test drive them for clearance as TireRack sent me the wrong hub centering rings... and I lost my ReverseLogic jack adaptor.

These wheels are designed to have lots of clearance for the AMG front calipers. The last set I ordered did not clear the caliper.


Here they are mounted on the rear.

Hmmm you sure them tyres are street legal ?? 75% of the tyre tread MUST Have tread above 1.5mm over in Europe ? Does that not apply there ??

And from a driving point of view , in the wet you will have hardly any stopping grip , and be as slippery as Obamas birth certificate !!!


DOH IGNORE THIS !!! JUST SEEN THE RACING USE BIT Doh

I think he' is using them for racing tires and not for general driving.

Look good though. Don't think I would dare drive on them. Lol

Yup, non-road use. My girlfriend (pit crew) will be hauling these tires to the event for me in the back of my '99 C280 Sport and I will swap them at the event.

How does the SLK55 do in autocross? The tires should definitely help as I think the OEM 245 rear tires really limit the chassis and engine in this car. Race slicks should provide a lot more grip. It can't hurt now that you've got the extra low end torque from the EuroCharged tune.

Does the heavy nose start to plow in autoX? Can you balance understeer with throttle? Chassis? Fun car to toss around? I can't imagine the brakes would give you any problem at all with the OEM 6 piston setup and semi-metallic pads.

Let us know if these fit.

I went and looked at them on the Tire Rack site. Nice.

The two things this cars needs on the track are brake pads with more bite and stickier tires.

The 275's fitted without any rubbing? You've mentioned in another post that you tried 285's but couldn't stop them from rubbing ...

CT_SLK: The '55 (at least my p30) is a great autocrosser. The OEM pirellis are terrible, but once I fitted proper tires (Dunlop Z1 Star Spec,) the car has been brilliant. I really don't feel the heavy nose plowing, and its very easy to throttle oversteer. The car has very good balance. Braking is amazing too, both with OEM pads and the Porterfield R4S I use now.

Nationals winning drivers have driven my car at evolution driving school (autox school) events and they all say the car doesn't really need any changes. It does what you want it to do right out of the box.

arter: TireRack sent me the wrong size hub centering rings. I get the correct ones tomorrow. Ill mount them and go for a test drive and see how it goes.

JudgeMing: I never tried 285s. You might be thinking of PropDr who tried it on different size wheels with different offsets.

If anything, I'm afraid the rears might rub the quarter panel at full suspension compression. Maybe I can try rolling the fender a bit.

I received the correct centering rings from TireRack yesterday! They sent me 75mm to 65.1mm, but all (modern) Mercedes use 66.6mm hubs.

I mounted all 4 wheels and drove around the block. Front wheels lock to lock seem to work fine. Rears also didn't rub going around the block. Looking at the compression coming down my drive way gave me a couple concerns in the event of full compression... but I'll explain with the pictures:

First off, these wheels look great. They clear the front brakes nicely and have a very clean design. I wouldn't use them on anything but an AMG just because the spokes are too thin and they need the big AMG brakes to fill the gap.


Here are the front wheels mounted. I needed random wood in my garage to get the front high enough to use my jack under the Reverse Logic jack pad adapter after lowering my car on Eibach springs. Specs: 18x8 ET35 Enkei PF01, 245/35/18 Hankook Z214



On to the rear wheels. Enkei PF01 18x9, Hankook Z214 275/35/18. With the car sitting normally, the wheels look like they poke out by about 1mm.


But when the suspension compresses, they tuck snugly into the wheel well. This was taken coming down my driveway at an angle.


Close up... the bumper stick-on flaps will have to come out. They go a few mm inward and hit the tire when the suspension compresses. Was never sure if I liked these flaps anyway. They were there when I bought the car.


View from the back. The wide rubber looks good! Note the rocks and debris stuck on the tires. Driving around the block drew stares from the neighbors because of the noise of rocks being thrown around by the super sticky soft/verysoft compound tires.


On another note, these wheels are incredibly light. The rears, even being half an inch wider and 275 vs 255 tires, feel MUCH lighter than the stock P30 wheels. They are listed as around 19lbs a wheel. I believe the stock P30 wheels are close to 27-28lbs and normal SLK55 16 spokes are around 26lbs.

I am considering rolling the rear fenders slightly just to be sure I have no issues at full compression. The first autocross event is on Sunday and I'll be sure to report how it goes!

Ideally, I would have wanted 245/35/18 in front and 275/30/18 in the rear. The problem is, no one makes a 275/30/18, and 285/30/18 would be too wide.

If anyone is looking to go with these for the road, I would just go with a 255 or 265/35/18 rear. Anywhere from 225-245 front. On the road, you wouldn't notice the extra rubber width, it would just be for looks. Also, on a non-lowered car, you probably wouldn't have any concerns with the sizes I'm using. Mine is lowered almost an inch all around with Eibach springs.

I think you are better off sticking to car-related posts.... if you must, try posting such thoughts in the "off-topic" forum where it belongs.

You are cutting it mighty thin in the back. If this was a road setup I think that two people and something in the back would definitely be cause for concern on rubbing on any compression. But for race purposes that won't be a concern and I think you've taken it to the max.

With your rears on 18x9 ET35 with 275 mm tires sticking out just a hint, one could deduce that 18x9.5 (which would be the better fit for 275 rubber) would need an ET closer to 30 to prevent excessive sticking out, which could also lead to unwanted paint damage because of debris coming form the tires hitting your own paint.

Thanks for sharing.

I am cutting it very thin. I wanted to fit the most possible rubber for 1 person for autocross only. The tires will be swapped at the event and will never see road use. Debris damage is a concern, but I use painters tape to prevent that while autocrossing, and will go back to 225/255s on oem wheels for the road.

You're going the wrong way with offset though. Lower number = further out. Higher number = closer in. An 18x9.5 ET40-42 would be perfect for the 275s. 9" is the minimum listed wheel for a 275 tire.

Member "PropDr" fit 18x9.5 ET42.5 (custom wheel setup) with 285s with minor modifications. 275 would've been easier to fit. There's actually a big difference between 275 and 285 as far as width goes.

Note: OEM Rear is 18x8.5 ET30. The oem rear fits perfectly in front with a 245/35/18. That's why I decided to go with 18x8 ET35 in front with the same size tire.



TSW has a range of wheels with 18x8.5 ET30 and 18x9.5 ET42 wheels that would work very well. Some are fairly light too. The reason I didn't go that route is that I live in Hawaii. I would have to pay shipping for wheels and tires from two different vendors and TireRack doesn't sell TSW wheels (and they also mounted the tires for free and heat cycled them for 15$ each. They even included the bolts and centering rings.)

Shipping cost for a set of wheels and/or tires is close to $300 for me. I also won a $500 TireRack gift certificate from the local SCCA region's banquet last month.

Which class do you Autox in? I was racing my JCW Mini in DS class, but this has more weight and HP. Also do you not feel you should raise the PSI a little? I would think the lower PSI you are using would shred your tires?

I started at the end of the 2011-2012 season in B-Stock, but ran the 2012-2013 season in ASP because I removed the secondary cats. All the cars in ASP last season were on street tires so it was fine.

This season, there won't be anyone in ASP, so I decided to make the move to SSM with the fast guys (two supercharged S2000s and a turbo fully SSM prepped Miata.)

Also, the tires had 34psi all around, so not sure what you meant by the low pressure.
