8" +35
10" +35

With 30mm spacers on, the relative offset currently is

8" +5
10+ +5

If you then want them to sit 25mm further out on the front and 30mm on the rear, with no spacers fitted you would need

8" -20
10" -25

Those are the sizes you'd need based on the information you've given, I would definitely double check your measurements of your current wheels to make sure the widths and offsets are accurate.

That seems extremely wide, can we see some pics of the car as it is at the moment?


Would I be wrong in wondering what and if it would be easier to get wider wheels with a less hard to find offset? Looks like my bank will break for what it seems I need

pics of these arches please?

low offset wheels are readily available, wallet depending.

you are aware you're negatively impacting on your handling by hugely widening your track with low ET wheels and/or spacers?

Will get pics.its a bodykit not just arches :)

Yeah but if I can get offset near middle of alloys I'm. Sure wouldn't affect it too much otherwise all trd mr2's (this isn't one) would have issues as you mention or do they?

It's going to be a looker so want it looking really nice and arches filled out to make its wide body really stand out more if wheels were flush and deffo wallet dependant aha :(

Rob makes a very good point, you could go wider but this is going to make things even worse.

If you kept the 30mm spacers fitted you'd need

8" +10
10" +5

Ah I thought spacers are worst thing one can use for making performance worse
At present it handles fantastically tbh so thought getting rid of the spacers would be a better idea

So spacers are better than using the correct sized wheels without spacers? :shock:

spacers or low ET wheels doesn't make a difference, if the effective ET is the same (i.e a ET0 wheel or ET25 with 25mm spacers)

the point being lower offsets increase the distance of the wheel from the steering pivot point on the front, so your wheel will turn through an arc as opposed to on it's centre (or close to) - imagine a hula hoop on a cocktail stick, where one end is stationary and the other travels through an arc like so -) the further out towards the end of the stick your wheel (hula hoop) is the lower your offset ---) and the bigger the arc your wheel travels through then you turn the steering, which messes up your handling.

you should really read a book on suspension (no offence intended here) before carrying out further modifications to your car. you can fit man sized rubber on an MR2 without going wide arch. and if you were to go wide arch (especially on the front) it should only really to be because you've gone wide track (properly) and thus need the extra space.

not read all the posts but i can chime in about spacers, i have 40mm spacers on the front and 60mm spacers on the rear, i was told (on here) that there'd be wheel wobble, the car would handle terribly etc.....the car feels exactly the same as it did before fitting them, Now don't get me wrong, i wouldn't be keen to take it around the track but for road use there is absolutely no issue with them at all, So much so that i'm happy just to leave them on as it means i can use any wheels i want rather than being limited to the stupid sizes required to fill the arch extensions :thumleft:

Oh don't worry no offence taken appreciate the simplified read how you out it and now I totally understand though I like the will turn through an arc now I see why it could affect things and appreciate the advise
I bet a read of suspension etc would be interesting so I'll have a gander around the net also :)

Wow that's some spacer sizes there what you running? Trd kit or wide arches?

Thanks for the comments and advise from your experience and yeah I won't be tracking mine some sprinted driving but no track high g cornering constantly anyways

I appreciate everyone's help and advise on this i finally understand how and what I'd need to do to fill the arches

I think I should start a build thread from what I'm starting with to what I end up with :thumleft:

Also gotta get rid of some unwanted tuning bits on car to fund it's respray and interior build I habe in my head :)

I have an AbFlug kit on mine, to be honest my rear wheels could probably do with coming out another 20mm, At the time i didn't have £1500+ to buy proper fitting wheels, This was also meant to be a temporary option for me but after running them without issue for hundreds of miles I decided just to keep them, they were just shy of £300 for all 4 (£270 i think once VAT and carriage was added). They are made to order so they take about 3-4 weeks, they don't tell you this though, I had to continually chase them up, actually, I'm assuming they are made to order due to the time they took and I don't suppose they keep fairly unsellable sizes like that in stock (despite telling me they had them in stock).

While trying to research them I had all manner of horror stories on here about spacers with no real world experience which was pretty frustrating but I can say with confidence they work just fine for road use, Somebody suggested swapping the studs on them for ARP ones and I would agree as the studs that came with mine were pretty nasty looking.

The best info i could find was the driftworks forum, guys using them for drifting without any problems but I can't say I'd be confident doing that kind of thing myself!

I did however take it to the drag strip the day after the spacers were fitted!! No drama to report!

Hope this helps :thumleft:

Oh, yeah get a build thread up!!

Ah cheers mate and love your 2 the colour choice is awesome aswell!! And the real world report also helps alot and I must admit yeah deffo not limited to wheel choice either
Tbh I think spacers are only way for me as could have full wheel choice like you say
I'll have to double check my measurements before I fork out though
Imagine having ordered some and then wrong size haha
Most common ET seems to be 35 everywhere so I'll choose spacers to suite that size wheel ET etc etc makes swapping wheels easier like you said

Thanks again Sheppy for the time aswell as everyone else

I'll sort a build thread
Hopefully everyone can come to love this car as much as it's growing on myself daily everytime I see it :)

I can't remember my offsets but I will check tomorrow as the rear wheels are off the car, I think they were 42 (wheels are 7" wide all round) on the rear, they didn't fit the car without spacers (in stock form) they caught on the caliper, the ET was advertised the wrong way round when I bought them ](*,)

The fronts I think are ET 35.

Yeah real world reports help, as much as i appreciated everyone's input it was completely wrong on all accounts, Physics dictate there is the same amount of stress involved on a wheel with spacers as there is with the correct size wheel, I did HOURS of research before buying them and if i'm honest it was all a little bit pointless :?

Yeah appreciate that if you can
If the offset of a wheel that is 7j is et35 and the ET is the same for 9j wheel
Which wheel sticks out more and can you explain why
As I guess I have to take into account the J size aswell as offset that goes with it if that makes sense?

Hope im not making myself look stupid lol

The 9" wide +35mm wheel would stick out further.

If you want to compare 2 wheels with different widths and offsets the easiest way is to use a calculators like this one http://www.1010tires.com/Tools/Wheel-Offset-Calculator

Well made hubcentric spacers are perfectly safe. They will be fine around a track as well - some Porsche's come with spacers from the factory for example!

The problem is there's a lot of cheap, badly made ones out there.
