Re: RA28 and Corona struts (bigger brakes) - queries and questions!!	Wed, 29 January 2003 16:46

Witzl, I'm using RT132 struts, in my RA28, with 16x7 F90's. I have chosen to go the Peugeot vented disc rotor though, but have had no problems with clearance other than tyre rub along the firewall on full lock, this however was more due to the fact I was running 225/50's (205/55's would have been a better selection). I used this strut type as they bolt up to your standard drag link, later model celica struts won't, so require more modification to fit if you decide to go this route. Can't comment on your 20mm offset problem? Are you talking about wheel offset? To measure your wheel's offset either with the tyre on or off, lay the wheel flat on the ground and place a straight edge over the wheel face. Measure the distance from the ground to the straight edge and devide this distance by two to get the centre line distance - MAKE A NOTE OF THIS NUMBER! Next, measure the distance from the back face of the wheel or tyre to the mounting surface of your rim - MAKE A NOTE OF THE SECOND NUMBER AS WELL!. Then simply subtract the first number from the second number and the remainder is your offset. Standard RA28 Celica wheels have a negative offset of 32mm, however you will probably find this to be less on your Simmons, especially if wider than the original fitment (alot of wheel offsets are more for ease of fitment than performance modification). My Simmons only run a negative offset of 5mm (I run 8's on the back with 245/45's too). Remember, if the first number is less than the second number, you will have a negative offset, and vice versa, if the first number is more than the second number you will have a positive offset. Now this previous statement is bound to cause controversy, as different books describe it differently. I'll happily stand by my description based on the fact that front wheel drive cars use large negative offsets in their geometry setups, and this supports my description. You don't need to be a genius to post here however, so bring it on people! You can have the offset of your wheels changed by Simmons for a negligable cost, but if they fit on your car now, I don't see the reasoon for doing this. Toquing the fastening bolts is best left to the factory, as changing the centres also involves a rather large o ring to seal the three pieces! Clint! [Report message to a moderator]
