Wheel help please


Recommended Posts

As Danny says with a 40mm offset the wheel would be significantly inboard - 22.7mm closer to the strut compared to a standard 6x14. Ronal.

Using 10mm wheel spacers will push the wheel out back to the equivalent of a 30mm offset, meaning it will only be 12.7mm closer to the suspension, but it will be 12.7mm closer to the edge of the wheel arch. Scrub radius will be similar to the standard wheel to

Just depends if you want to use a spacer or not. Problem is that there are not too many wheel options for Mantas with a sensible offset these days.

All depends on width tbh, but I can speak for 17” and 7.5” on Front, 8” on rear.  I had my alloy offset made at ET40 as no one had a definite answer when I was making enquiries what actually worked. My tyre widths are 215 Front and 235 rear, @ 40 profile.

Front as in pic 1 is ET34 (6mm spacer) 7.5x17 with 215/40R17 tyres

Front as in pic 2&3 is ET32 (8mm spacer) 8x17 with 235/40R17 tyres

Pic4 car out on ground is sat with the above.

However, I have removed the spacers on rear, so that it’s ET40  as a test for a mate on FB and it works! clearance is tighter, but no worse than front to shocks. After all, clearance us clearance as they say. I don’t have a pic on hand.
 

so if I was to reorder the wheels now, I would order fronts and rears at ET35. Funnily enough this is exactly what I originally was going to go with, but when ordering I went 100% caution as I had not been there was no definite answer with clearance pictures.

Hi jess did you use longer studs with your spacers

Hi Matt

Yes you will need longer studs. Some of the spacers kits come with longer studs. I’m using H&R spacers which come with 10mm longer studs for the 5mm spacers.

It’s a bit of a pain to change the studs but I was upgrading the whole front suspension, and brakes (why I need the 17inch rims) so I already had everything in pieces

Yes all wheels studs was replaced when I refurbished the suspension, simple knock them out with a big copper hammer. They are the same as fitted to mk2 escorts got mine from Burtons

I got the spacers off ebay I think the seller was tunershop-worldwide, which is in Germany. When I’ve checked they were actually cheaper at  dcperformance.co.uk. I think there are a lot of places selling H&R spacers but there are other brands to, but not all come with the longer studs.

With 10mm spacers you may be better having ones with the built in spigot rings. The thinner spacers don’t need them as the hub spigot is long enough, but as you go thicker I think its better to have the ones with built in spigots to locate the wheel.

Cheers guys atleast I know they will fit with spacers really like the wheels I've found so that's a big help

Indeed mate, 5mm should be fine. Depending on tyres you could go out a bit more

Yeh 205 40s need to think about tyres once  I've got them fitted properly bear in mind I never moved car for them to settle a little what's your thoughts on tyre size for them

I’ve gone for 7.5J rims so I’ve been thinking 225/35x17 as it is the same diameter as the standard, but there is only really Yokohama who make a tyre in that size. I think that might be a little wide for a 7J rim, and the 35 profile might be a bit harsh as well. The other option is 215/40x17 which should fit on a 7J but they are 14mm larger in diameter so the speedometer will under read by about 2%, so the speedometer will show 29.3mph when you are actually doing 30mph. The good thing about 215/40x17 is that it’s a common tyre made by lots of manufacturers. 

I’m going to dummy fit the bare rims and measure up before deciding on tyres.

See my pics above I use 215/40 front on a 7.5” rim.

The std rolling radius is too small imo for the arches. They need a 1” bigger wheel that will also raise car slightly for those bloody speed bumps. 
Also Janta likes a bit of Rake, so slightly bigger rear mate car sit right, also imho. 
 

I did originally go with 215/40 all round as the 225 option was not viable due to availability/price as it’s a pretty rare size. And that did not look too bad tbh.

Finally finished the front suspension, brakes and wheels.

I’ve gone for Speedline Mamora SL2 17x7.5 ET35, with a 5mm spacer and 215/40x17 Pilot Sport 4’s

Good clearance all round on the front suspension, could go a bit wider but tyre getting close to shock absorber when suspension is unloaded. Plenty of room under load though.
