The Sparco F-10A is a 270mm five spoke wheel in suede. Part number SSW015P270SSN.

270mm is the reason to look at this one. Most road and fast road wheels are 330mm or 350mm. Dropping to 270mm makes the steering feel quicker for the same rack, because you are turning a smaller circle for the same lock, and it frees up room between the rim and your thighs in a car where you sit low with a helmet on. It is a competition wheel rather than a road one, and in a car with heavy unassisted steering it will feel like hard work at parking speeds.

Specification

270mm diameter, flat dish at 0mm, so the rim sits where the boss puts it with no reach towards you. Five aluminium spokes in black. Suede grip.

Note that the horn push is not included with this wheel, which is normal for a competition item and worth knowing before it arrives. If the car needs a working horn for an MOT, factor that in.

Suede grips better than leather, especially in gloves, and marks faster. On a competition wheel that is the right way round.

Fitting, and the part most people miss

The centre is drilled twice. There is the usual six hole pattern on a 70mm PCD, which takes any standard Momo, OMP or Sparco boss, and there is also a three bolt pattern on a 50.8mm PCD for a quick release.

That second pattern is the reason Sparco list this wheel for single seaters and sports prototypes. If you are running a car you have to climb out of quickly, or one where the wheel comes off to get in at all, the three bolt quick release is what you want and this wheel is already drilled for it. Tell us which route you are taking and we will supply the right boss.

If the car has a driver airbag it has to come out first, with consequences for the MOT and your insurance. Raise it with us before ordering.

Steering wheel size and fitment guide

Three numbers decide whether a wheel works in your car: the diameter, the dish, and the bolt pattern. The bolt pattern is the easy one, because almost everything here shares it.

The bit that makes this simple: 6 x 70 mm PCDMOMO, OMP and Sparco all drill their wheels on a six bolt, 70 mm pattern, and so do the boss kits and quick releases that suit them. That means a MOMO wheel goes on an OMP boss, and a Sparco wheel goes on a MOMO boss. You are choosing on size and feel, not on compatibility.

Diameter

Every rim below is drawn at true relative size. Forty millimetres looks like nothing written down and is very obvious once you are sat behind it.

380340300260

Smaller means quicker and heavier. You turn less to get the same lock, and you work harder to do it, because you have less leverage at the rim. On a car without power steering that trade bites hard at parking speed and barely at all once you are moving.

Diameter Brands we stock What it suits
250 – 270 mm OMP, MOMO, Sparco, Reverie Single seaters and tight cockpits
280 – 300 mm MOMO, OMP, Sparco Race cars with quick racks
310 – 330 mm MOMO, OMP, Sparco, Sabelt Road-based track cars
340 – 350 mm MOMO, OMP, Sparco, Sabelt Closest to a standard road wheel
360 – 380 mm MOMO, OMP, Sparco Classics and cars with no power steering

350 mm is the most common size on the site by a distance, and it is the closest to what most cars left the factory with. If you are replacing a standard wheel and you are not chasing a specific change, that is the safe starting point.

Dish

Dish is how far the rim sits toward you from the mounting face. It is the number people forget, and it is the one that decides whether you can still get in and out of the car.

Dish type What it does When to pick it
Flat Level with the mounting face When you are adding a quick release
Shallow Slightly toward the driver A small adjustment
Semi Noticeably toward the driver Column set a long way forward
Deep Well toward the driver Classics with an upright column
Adding a quick release? Go flatterA boss kit and a quick release together add a real stack of depth between the column and the rim, and it all comes toward you. If you are fitting both, a flat or shallow dish wheel usually ends up in the right place. A deep dish on top of a quick release can put the rim in your chest, especially in a fixed back seat.

The exact dish figure in millimetres is listed on every product page under Wheel Dish Size, so you can compare like for like rather than going on the type name alone.

Spokes and grip

Spokes Typical use
2 spoke Classic and vintage cars. Clear view of the instruments
3 spoke The standard, and what almost everything here is
5 and 6 spoke Mostly styling. Popular on classic restorations

Grip material is mostly preference, with one practical point: suede and alcantara give the best feel in gloves and the worst life in a road car that lives outside. Leather is the sensible all-rounder. Wood and polyurethane are for classics, where the look is the point.

What else you need

A boss kit, always

An aftermarket wheel does not bolt to your column. A vehicle-specific boss kit adapts your column spline to the 6 x 70 mm pattern, and there is one for almost every car. Ours are listed by vehicle, so search your car and year.

A quick release, if you want one

The quick release sandwiches between the boss and the wheel, so you still need the boss. It makes getting in and out of a caged car far easier and it is worth having if you are climbing over a door bar. Remember the depth it adds when you pick the dish.

Horn and buttons

Some wheels come with a horn push and some do not, and it is listed on every product. If your car needs an MOT, check before you order rather than after.

Tell us the car and what you are trying to changeWhether you want it quicker, closer, further away or just tidier, plus whether a quick release is going on. Diameter and dish work together and it is easier to get both right in one go. Call 0115 989 3488 or email Sales@GSMPerformance.co.uk.

Diameters, dish types, spoke counts and materials are read from our own product data, checked 2 August 2026. The 6 x 70 mm PCD applies to the MOMO, OMP and Sparco wheels and boss kits we stock; the Reverie carbon wheels and some classic patterns differ, so check the product page.

Do I need anything else to fit this wheel to my car?
Yes, a boss kit (also called a hub). The F-10A bolts to the standard 70mm six-bolt pattern shared by MOMO, OMP, and Sparco boss kits, but the boss kit itself is specific to your car’s steering column. Find yours in our boss kit range, or tell us your car and we will match it for you.

Is a flat wheel right for my driving position?
This is a flat wheel, so the rim sits level with the mounting face and your reach to the wheel stays as the boss kit sets it. The right choice when your driving position already suits the standard reach. If you are not sure which dish depth your driving position needs, our steering wheel dish guide walks through it.

Does it come with a horn button?
No, this wheel does not come with a horn push. Most installs wire a horn button into the boss kit or dash instead. Tell us your setup and we will point you at the right parts.

What happens with my airbag and MOT?
None of our motorsport wheels carry an airbag. On a car that had one as standard, the dash light stays on after the conversion unless a bypass resistor is wired in, and an illuminated airbag light fails the MOT. Tell your insurer about the change too.

How do I keep the suede grip looking fresh?
Suede gives the best grip of any rim covering, especially in gloves, but bare hands will gradually polish it smooth. A soft suede brush every few weeks lifts the nap back up. If the wheel is for a daily driver used without gloves, consider a leather-rimmed alternative.

Is 270mm the right size?
270mm is a competition size intended for formula, kit car, and hillclimb use with quick steering racks. On a standard road rack a rim this small makes low-speed steering very heavy, so we would not recommend it for a road car.

Can I use it with a quick release?
Yes. Any quick release made for the 70mm six-bolt pattern takes this wheel, and the quick release then mounts to your car-specific boss kit. See our quick release kits, or ask and we will spec the full stack for your car.
