Wheel Fitment Guide for Subaru Impreza New Age GDB(Bug/Blob/Hawk)

Width: 6.5" to 7"
Impreza New Age Wheels
When you’re looking for aftermarket alloy wheels, it is common to change the sizes from the original factory wheels. There are a variety of diameters, widths and offsets that will fit, but you must get a wheel that matches the original PCD of either 5x100 (all WRX GDB and -05’ GDB STI), or 5x114 (05’+ GDB STI)
We would recommend 18” diameter with GDB, as this will look great, allow for big brake clearance and let you fit the most suitable tyre sizes for increases in power, 17” is reserved for super low GDBs.
How wide and which ET you go for depends on the look you’re after, what tyres you want to fit and whether you just want a simple straightforward bolt-on fit, or you’re prepared to put some work into adapting the suspension and bodywork to suit.
We can supply wheels in a big variety of sizes, from exact replacements for your originals, up to huge, wide and deep dish drift style wheels. Here’s some examples of different sizes and styles of Work wheels fitted to Imprezas to give you an idea of the look and range of what’s available.
You can find direct links to the Work wheels to fit the Subara Impreza at the bottom of this page. If you’re still not sure of what you need, just give us a call or drop us a message and we’ll be happy to help.
Recommended Wheel Sizes
Any of the below wheel sizes will go straight onto your Impreza without the need for any changes. A great choice if you just want to upgrade to a nicer looking, lightweight wheel.
The most common of fitments for the GDB Impreza, is 18x9.5J width all round. This will give you the “drift” wheels in models such as Grid, Torque etc (concave spokes) - making for a great looking, aggressive fitment. You’ll require an arch roll front and rear. For the least hassle we recommend a 235/40 tyre and a couple degrees negative camber.
Front brake caliper clearance is the only other issue. If you have the bulky OEM Brembo brakes, you will need a 6mm slip on spacer with 18x9.5 Grid. Any aftermarket brakes (AP/Ksport/D2 etc) don’t need a spacer.
With ETs lower than 35 with a 9.5J wheel, and for 10J wheels you’ll require substantial arch work (flaring/pulling) or wider bodywork (fenders/arches). Mainly reserved for track cars, the wider wheels enable you to use really wide tyres to get maximum grip.
We can also help with wheel fitment for custom arches/bodykits and supply any wheel spacers needed.
