E21 316: More Open Arch Surgery! Wheels finally on...

Got the grinder out again today and tackled the job I haven't been looking forward to - cutting away the other rear wheel-arch. Progress was quick and smooth for a change, I guess because I had an idea of what to do now, but I think the lower profile tyres played a part. If only I'd bought them first time round I wouldn't have had to butcher the n/s quite so much. A good notch had to come out at the bumper shut-lines as these were the main bits sitting on the tyre, but less of the outer lip had to be cut away and the arch looks a lot smoother than the last effort.

The main problem with scrubbing was coming from the inner skin of the arch and the best way to get that off was still to peel it back, cut wide flaps in the metal using tin-snips and work them with grips until they snap clear.

It's been quite a bit of effort and hacking away at the car was heartbreaking, but at last the super fat wheels are on and no scrubbing whatsoever. Now to see about neatening up those arches...

E21 316: Front wheels fitted - the easy part.

No fouling on the pulled arch-lip with these skinnier tyres, but the front valance was still just about catching so, with the arrival of the new spacers, I thought I'd get the fronts boxed off before starting the arduous task of the other rear arch. Sadly, my camber-plates have yet to arrive, I guess they must be stuck while Customs & Excise figure out what they are.

Thankfully, the amount of valance that needed cutting away on the n/s was only about 8mm and I didn't have to remove the bumper after all. I did my best to follow a natural curve, not sure if I took a little too much near the bottom. Interestingly, the o/s of the front valance didn't contact the new tyre at all and the fender does not extend past the bumper. I wonder if the n/s wing has been replaced at some point giving a slightly proud line. I matched up to that line when repairing the lower-valance last summer, so that would explain why it was catching the tyre too. Either way, the o/s/f arch required no grinding at all, so a little more pulling and the fronts will be ready for smoothing in.

I've also been driving round the last day or two with NASCAR style staggered wheels - 16s on the n/s and still 15s on the o/s. The car steers great to the right, but is a bit recalcitrant going hard left. I must find time to wrestle that other rear arch on Monday or it'll be like this for a while.

E21 316: Stretched Toyos first try + more spending.

Tried out the 8Js on the front with the new 195 Toyo T1Rs using 20mm spacers and there's a lot more room at the arch-lip now. The tyre doesn't catch at all turned hard-left, thought it would going over a bump. Hard-right the tyre is still catching the front valance slightly, but about 1cm cut away should be enough now and a little off the fender where it protrudes from the bumper - none of the bumper itself though. I had hoped to get away with smaller spacers on the front, but even with the 20mm spacers from the rear, the inside rim of the wheel is still 5mm inboard of the 15x7Js and there is not a lot of headroom.

I just haven't found time to try out the 9Js on the rear today as the valve is bust in one and on the other, about 6 inches of the bead has just been refusing to seat. My leg just couldn't take any more foot-pumping so I got hold of an air-compressor from a friend and took the tyre to nearly 90psi this morning, but it still wasn't having any of it. Eventually, after two goes deflating the tyre almost completely and trying to brush in soap between the tyre and rim, then taking it back up to about 65psi, the bead finally popped. The maximum pressure rating on the tyre is 50psi, though it says use no more than 40 to seat the bead, so it just goes to show that when the seal is tight enough it can take over twice that and still not seat. Bead-blaster machines can jet up to 200psi in one go and that doesn't even shred the tyre to bits so I'd be keen to know at what pressure a good new tyre would rupture at. Even so, always take the utmost care when inflating tyres past their rated pressures at home!

Apart from 4 new valve-cores (£2.99) and a valve removal-tool (£4.99) from Halfords, I've had to do yet more spending on parts as the project can't move on without them and I want to be getting somewhere near finished next weekend when we have the bank-holiday off. First up are adjustable camber-plates for the front, a must for style and it will likely give me a bit more room to play with before starting to cut. They're not approved for sale in the UK, so lets hope they make it here from Poland before the weekend - fingers crossed eh! Looking forward to these, though quite pricey @ £105 delivered, but whatever, they're the only ones of their kind. It's also time to stop digging my heels in and buy another set of spacers to go on the front, swapping the ones over from the rear is becoming a chore. I'd hoped to get some alloy ones to save hub weight, but again for easy access, the right centre-bore without more spigot-rings and to get the bolt-on kind I want, yep you guessed it, more steel ones. Another £59, oh well, roll on next weekend.

E21 316: Slight arch foul!

As you can see, the arch was sat on the tyre something awful with the 9" wide wheels at the back and the 225/45/16 rubber on...

A bit more arch persuasion...

Credit card clearance!

Or is it? The arch is still sitting on the tyre a little. The car just about rolls, but there's nowhere for the tyre to go either on a bump or with the weight of the driver...

It looks very flush and tidy, but something drastic will have to be done.

E21 316: Rear Wheel Spacers + Arch Rolling Kit!

With the engine now back in fine fettle [we hope!], I couldn't wait to get back on-project and spend a bit on stance, so I've started with these 20mm spacers for the rear wheels. I'm not sure if it's an illusion of the E21 body-shape, but the rear wheels always look a bit tapered in from the front ones, so these spacers should primarily even up the front/rear track or even bring the back wheels a bit further out than the front, as it should look. They'll also help make my rather skinny 7J wheels look a bit fatter and get the arch-clearance a bit tighter - and, of course, will make fitting fatter wheels [which is going to have to happen at some point isn't it] easier in the future.

In fear of the spacers pushing the wheel out too far and causing the outside of the tyre to contact the wheel arch, I also bought a wheel-arch rolling kit. It's about £100 to have a pair of arches rolled professionally and, as mine is a work-in-progress and I'm not 100% on the setup I'll be using, I decided £97 for my own kit will definitely work out cheaper if I need to keep on rolling them out as I go lower and wider...

French made spacers are nicely machined, but billet steel and pretty heavy.

Deemed too wide for extra-long wheel-bolts, these babies have two sets of holes and bolt on to the hub by themselves.

Rear wheels slightly proud of front ones as they should be, but a slight loss of negative-camber.
