There is a conversion kit (801182) to change the Impulse PRO to 705. However due to the respond and the price itself, Serpent has decided not produce these conversion kits anymore. The conversion kit actually includes the following;
Conversion set to convert all chassis parts of an older type Impulse PRO into the new 705 version, like chassis, carbon radio tray, fuel tank, battery holder, anti roll bar, various mounts and fixing parts, full manual and spare parts list of the 705
Anyway, it's pretty complicated to get the Streetspec to the same as the 705. You need to change the Impulse Streetspec to an Impulse PRO before you can change it to 705. The Impulse PRO (as with 705) has front and rear shock towers. Spacers on the rear uprights, one way front etc. All in all, it's not worth to do the conversion as it will turn out to be about the same price or more expensive than a brand new 705 kit... In any case, the conversion kit does not come with the Centax II clutch and the new lightened 2 speed gearbox. So you need to get these separate which will cost you a bomb.
What you could do is to keep the Streetspec as spares. The arms, knuckles, bearings, front bulkheads are the same. One useful item on the Streetspec is the front gear diff which you can use on the 705. Useful for smaller and more technical tracks.
Good luck and let us know what happens
