Took my car for it’s first MOT (under my ownership) on Saturday. I have only had the car for about 4 months now and got it serviced when I got it, so I didn’t do any prep apart from the usual lights check. The car passed ok apart from a comment that there was a maximum of 1mm legal tread left on my 2 rear tyres!
I knew they were getting low (not just that low!) and had been using this as an excuse to start thinking about new alloys and tyres (as you do). Anyway, it appears that I need to start thinking a bit more seriously about it than I thought.
If I am going to go for new alloys then I would ideally like to get 19s. I had already narrowed my alloy choice down to one of these 3 -
ACS 3 Racing (rep) –
ACS 3 (rep) –
Finichi Firenze –
The car already has MV1s on it, and as much as I love CSLs I have ruled them out as they are kind of similar to what I have got (and everyone seems to be getting them at the minute). I always liked ACS 3s as they are more of a traditional BMW alloy rather than the aftermarket look of the Finichi's, so I may be swaying to the ACS 3s. I am however unsure if I prefer the ACS 3 clean look or the racing look (with studs).
Alloy choice is obviously a personal preference thing, so the point of this post isn’t for opinions on this (although all comments are welcome), but rather to help me understand offsets with regards to the staggered setup on my 325Ci Sport and a few other things. So, the questions are -
1. My car has the staggered setup – 8j up front with 225/40/18s and an offset of 47 (I believe), with 8.5j on the rear with 255/35/18s and an offset of 50 (I believe).
The recommended tyre size when going for 19s seems to be 235/35/19 but I am confused by the offset bit as whatever reps I go for will have the same offset all round and not the staggered setup (and different aftermarket wheel types have different offsets).
Depending on my choice of alloy, the size seems to be either 8j or 8.5j all round. How do I know the correct offset I should be looking at for either of these?
e.g. the 19” ACS 3’s I like have an offset of 35 which is much less that the offset of my current wheels?
2. Will there be a huge difference in looks at the rear of the car, in terms of width and positioning in the arch, between my current 8.5j with 255/35/18 and an 8j with 235/35/19?
I’m guessing the difference in arch position would be less with a 8.5j with 235/35/19?
3. The car has the Sport suspension and I will not be lowering it further. I like the way that the ride height is at present, so will sticking 19s on to the standard Sport suspension without lowering it look out of place, or should ride height be pretty close to the way it is now?
4. Does the quality of alloy reps differ widely? Has anyone used ‘wheel-base.co.uk’ ?
