Rear diffusers - how do you cope?

I don’t consider my Supra too low but some of the roads round here see me scraping mine all the time, especially when putting my foot down. How do you cope, is it normal and a case of put up or shut up, or would it be better to stiffen up the suspension or something else?

Shameless attention pic to show height of Supe

I've installed air cups for height issues. Worth a look if you're having issues in and out of car parks etc.

These are on the shopping list but I haven’t researched them, I imagine they are expensive to purchase and fit? My main concern with the scraping is more when driving on normal roads, they’re terrible in Surrey. There’s too many unavoidable bumps in the road that causes the Supe to bounce around and scrape the diffuser

I have had shineauto diffusers for quite a few years now, on my old car I had the height quite flat and the diffuser used to scrap on speed bumps, now I have the TT the car is slightly more raked and the front sits lower but as a result the diffuser is at a bit more of a favourable angle for bumps

Not too bad. About a grand in parts. Then just labour.

I have HSD coilovers. So had to extend the leg slightly as the cups made the reach too long. But typically it's basic modifications if any is needed.
