I wanted to ask you a few questions about your wheel fitment, specially in the front. I got a set of Potenza S007A in 235/40r18s and Id like to run them in a square configuration with either a 18x9 ARC-8s or EC-7s in an et42 like yourself, I’m not planning to track the car and my suspension is stock. I know a lot of people run the 18x8.5s in either in an et35 or an et45 (with maybe a 3mm front spacer, that turns that et45 wheel to a et42), this seems to be a fairly common Fitment for the f22s; However, I like the 18x9 rim because it does have a slightly different profile look than the 18x8.5 version of the same wheel. My question is in regards what you think would be the minimal front spacer size needed to clear the front strut with a 235/40r18 tire, given that this tire is roughly 3/4” narrower than the 255s you’re running, also how much camber do you think will be needed with the narrower tire. Thank you. |

Hey man! Thanks for the love Apex always recommends the 10mm spacer on the et42 9" setup. This allows for the inner clearance to the strut. I'm not sure on stock struts exactly how the fitment is, inside, but if using a 235 tire on that setup on stock suspension I think you'd be just fine with the 10mm spacer. The reason I'm opting for a 7.5-8mm spacer is because I've created a bit more clearance inside by installing a shorter coil spring which allows the perch to raise high enough to help (as pictured). Without the shorter spring on my setup, the tire would be much closer to the perch. D

Im trying to keep the tire away from the fender as much as posible, worse case I’ll roll them a little. Thanks for the help. Btw, I love the color contrast between the yellow calipers and the black paint. |

From Apex "Front & Rear: 17x9" ET42 with 255/40-17 tires •Available in ARC-8, ARC-8R, and EC-7R designs. •Front 8mm or 10mm front spacers required (hub extender required). 12mm can also work with negative camber dialed in. •Rear negative camber and/or rolled fenders highly recommended" Here's a 17x8.5 ET40 setup which I think is pretty solid if you're super worried about fender clearance. The take away on the 9" + wheels is typically that negative camber is required, weather minimal at -2* or more.. Wheels: Flow Formed ARC-8 wheels in Satin Black 17x8.5" ET40

Hi there,
I had a question regarding the megan racing rear links. Are all the joints monoball and sealed with rubber boots or are they open? They appear to be half the price compared to SPL parts, but the SPL one also look to be open spherical bearings which isn't ideal for road use. Considering some upgrades but the car is daily driven in wet UK conditions! Great build. Thanks. |

They're steel balljoints with rubber bushings. The thread locks are also protected but rubber boots. Great product for the price, imo

I manage to finally fit 255/35R18 (hankook rs4) NT03RR 18x9 ET45 with 17.5 or 18mm spacer up front with my KW Clubsport 2 way. Haven't drove it yet, but seems to have a tiny more room left.
-3 to -3.1 front and -2.25 rear. Note: I am xdrive and don't have m4 lca. |

Update, sort of..
Maintenance has been a focus for me this spring, with COVID related delays with tracking, and overall time to get out has been difficult.. As things are reopening I wanted to have the car ready, no maintenance spared, so I took care of the following; Brake fluid flush (Motul RBF660) required 3 new bleeders MT Trans flush (Redline D4) Coolant expansion tank hose (OEM, they age/crack) Oil Change (LiquiMoly) Diff Fluid flush (Fuchs Sintopoid 75w90) Coolant checked for PH and all good Checked all piping/clamps for seal Torqued all suspension hardware (you'd be surprised what was slowly coming loose, namely front strut top hats/sway bar links) Suspension/Chassis clean up Retorqued all rotor hardware, added safety wire this time During this time I also had an opportunity to swap my MP LSD to a Quaife LSD, more to come on my after thoughts. It was a straight trade with a friend who was trading his m235 in so I basically covered labour and got the Quaife for “free”. Sweet deal, really liking it so far. Have an appointment at Powersports Garage @ Calabogie Motorsports Park tomorrow for a real track-alignment, done with string/laser etc along with a corner balance. This is something I've put off for time, and it should really help seeing that my previous alignment was rushed and done on a traditional rack.. Track days are starting up, have 3 confirmed bookings for Aug/Sept/Oct, currently searching for some in between events to attend. D

This is 17.5mm spacer. Theoretically, 15mm spacer could work. I stuffed 255/40R17 RE71R into a 17x8 et40 with 10mm spacer and there is no rubbing. The only things that changed mathematically are the tire width and the wheel. Hankook rs4 is wider than RE71R by .4" and shorter by 0.2in. The wheel should clear with 15mm spacer. Update: I have 5-6mm space between tire and spring with hankook rs4 and 17.5mm spacer. tire will touch if I use 15mm spacer. If I used RE71R and 15mm spacer, I would have 1-2mm. clunking sound coming from the front wheel areas. likely end links. |

If doing front links, grab a set of Hotchkis adjustable units. They're solid steel bushings with adjust-ability. Had mine on for the third year now, no issues.

Had a time attack event at TMP this past Saturday. First shake down at this track, needless to say.... I need more power now lol. Managed a 1:23.11 on my shakedown session, car and track got hotter and hotter, and I couldn't make up what I gained in line choices for what I was lacking in straight line power. IAT's were sky high, DME only gave me 7-9psi from 5k and up and hardly any timing advance (6-8* tops). This will change when I go back in the fall, though..
Car felt great otherwise with the new alignment/corner balance but noticed how much I need the added power at this track. Getting passed by CTR's on the straights like it was nobody's business Alignment specs are F -3.1* 3mm toe out, R -2.2* 1mm toe in 255F RE71R on 18x9 et42 (10mm spacer) (picture after fender pull/roll) 265R RE71R on 18x9 et43 Some of the boys rides, M3 DCT, 295 square Trofeo R's, Trophy BBK, full downforce car: Rocco RMP's iR, beyond spec car (has tune and other changes from iR spec) OG M2 DCT, Trophy BBKs, 295 square Trofeo R's, cage/seats etc M3 CS, Trofeo R's and Pagid pads
