Sorry, that was front.
Put it at fender level at the back and it seems fine in the animation,(camber tucks it in) though clearances are small - so you might be all good.(y)

Love your work.

Yeah, hopefully it will be okay. I'll let you know if I get any rubbing - the roads around here are garbage so I'll find out pretty quickly I reckon 😅

Are you planning to run aftermarket wheels at some point?

That will probably be my next upgrade.
I'm accumulating a list of potential candidates - those 57DR's are one of the options.;)
Not really sure what tyre/rim size/offset I'll go with, think the 57DR's are only available in +37 offset(?).

Pretty sure they had a +38 but in a 9.5 available locally.

Personally, I reckon that's a bit too much tyre for these cars but plenty of people are jamming them under there..
I believe the place I got mine from has some other styles too.

Day 2 with Pro Streets, loving how the car handles. Definite step up from the OEM strut/STI spring setup I had previously. No penalty in comfort, it just feels a bit different and actually a bit more sophisticated and balanced. I can tell the front springs are a bit stiffer than my previous setup but it feels 'sorted' and still has good compliancy.
Still have to get to some back road driving to see how it copes with poorer/uneven surfaces at higher speeds.

FWIW here's a comparison to my vehicle with the STI springs which gave a mild 10mm drop.
The MCA coilovers are currently about 13mm lower - so about 23mm below stock. I'll let things settle and see if I want to change anything.

Previous setup with STI springs:

Wouldn't you be able to set your RCE coilovers(?) wherever you want, within reason?
What's an RC kit?

It's a trade off with single shock body coilovers. Adjusting the ride height will fundamentally change my bump and droop split. If I raise the car more, I will be quickly running out of droop travel.

You don't need massive amount of droop travel, but for tracking application rear droop travel is essential. Cus lifting a rear wheel when the car is loaded up can cause a sudden snap oversteer.

RC kit = roll center correction kit. I've done some measurement on @Chris1 stock car, it turns out that factory FLCAs static angle is 4° non inverted. Lowering the car will reduce that angle, and typically we don't want that static angle to fall below 0° (or positive degree of inverted FLCA angle). My car is 25mm f and 20mm r lowered, so I needed to have a RC kit to correct back my front geos.

MCA recommend having at least 50mm of droop extension. They say If you don't have that with your chosen setting, lower until you do and then raise with the bottom mount (which normally they say not to touch).
I still have to lift the car again and set the torque on the knuckle bolts (didn't have the right socket), so I can check what droop I currently have vs ride height.
Its a bit hot in the garage today, but I'll get to it on the weekend.

Hey @Jules Mac what camber did you end up with on the rear and what camber did your shop dial in at the front?
I haven't touched the camber plates at the front and only have the lower camber washers that came pre-installed - the ones labelled '14-1' (MCA also provided washers labelled '14-2'). This has introduced a slight amount of camber at the front - which may be partly responsible for the improvement in handling.
I was going to wait and see what the wheel alignment shop gets for rear camber and then dial in an appropriate amount for the front. Not sure if the front should be less, equal or a bit more than the rear? Currently the rear has obviously more camber than front.
Even without any wheel alignment I'm really impressed with how the car handles on the Pro Streets.

Hey @Tobes

Unfortunately, I am mechanically incompetent - basically, I told them what I wanted and said use your better judgement/knowledge to set it up accordingly.

Short answer: not a clue.

I do apologise for my ignorance and complete lack of useful advice/information to assist you.

Where are the camber tops set on the front - any chance of a photo?
Do you know if they changed the lower camber washers - might be able to tell by what you got back in the little velvet baggy?
Since I still have to torque the front knuckle bolts I was thinking of putting in the 14-2 washers to see what that changes.

That's not what I was expecting.
They haven't added any camber at the front, only the approx -1 deg provided by the camber washers pre-installed by MCA.
I haven't touched my camber tops and they are sitting in the middle like yours. I also have the same camber washers left over, the ones marked '14-2', which would potentially provide approx -2 deg of camber.
Given that dropping the suspension ~25mm will increase rear camber to about -2.5 deg, I wonder why they didn't add a bit more front camber? Was there any alignment report or indication what they measured?
Having said that, my car drives fine with the same setting you have.
I was planning to increase front camber to about -2.5 deg when I got my alignment.

MCA set mine up like this:
Front ride height: 346mm from centre of wheel to fender
Rear ride height: 347mm from centre of wheel to fender.

@Harpdog do you happen to know what camber settings MCA set with your Pro Sports?
I'm just canvassing for ideas/opinions on where to set mine.

@chopsticksguru what camber did you end up going with?
