Couldnt agree more with Dan. You spend all of your time in the car so makes sense to improve the space your in. For me, my best modification was the 197 steering wheel for my 172 to replace the 172s 9yr old, part melting steering wheel. Updated and cleaned up the car for me as far as i was concerned.
The next best modification was a full set of new tyres (Toyo T1Rs) and a 4 wheel alignment.
I regret fitting Eibach lowering springs in hindsight, sure it made the car handle alittle better and look nicer but the ride was alot harsher in comparison. Even my 200 Cup isnt as harsh as my 172 was on Eibachs.
So if you bought a car with shite tyres, youd buy a new steering wheel and boss 1st?
