The Mazda MX-5 based MK RX-5 has a 2363mm wheel base (front to back).
The track of the standard vehicle has slightly different measurements between the front and rear if you are using 13" MK VR-1 Wheels because you need a 6mm wheel spacer on the front to clear the wilwood brake caliper. Our pre-bent wing stays have been made to accommodate this upgrade, regardless if you have the 4 pot brake calipers or not.
Using the standard ET35 7" wheels from the Mazda donor car, with standard front brake calipers, the RX-5 measures 1670mm at the floor including the bulge for the tyres.
If you are using the 13" VR-1 Wheels and Wilwood 4 pot front brake calipers, then in reality you can add a further 6mm each side thus making the width of the front track 1682mm.
Weight of the RX-5 140 is typically 570kg with a full tank of fuel in IVA trim.
Note : Depending on the specification of the vehicle this can vary (windscreen, roll cage, weather equipment, turbo etc etc).
If you were trying to fit the RX-5 on a Brian James Minno or a PRG mini-sporter trailer which has a bed width of 1650mm, then you would need to fit space saver tyres. This would make the track of the front of the Indy RX-5 1580mm on standard calipers, or 1586mm with Wilwood front calipers.
Note: The Mazda space saver wheels do clear the Wilwood 4 Pot calipers when used with 6mm wheel spacers.
